Is It Safe To Get A Mammogram During Pregnancy?

Updated Feb 20, 2025 | 02:00 AM IST

SummaryMammograms use low-dose radiation, with a single screening exposing patients to about 0.4 millisieverts—equivalent to seven weeks of natural background radiation. Only 1 in 3,000 pregnant women are diagnosed with breast cancer.

Pregnancy is accompanied by a lengthy list of do's and don'ts—take prenatal vitamins, no alcohol, exercise carefully, and eat well. But what about when an unplanned health issue presents itself, such as the necessity for a mammogram? For most women, this might not even be something they think about until they are in a position where breast cancer screening is an option.

Perhaps you're over 40 and in need of your yearly mammogram, or perhaps you have a history of breast cancer in your family and you want to keep your screenings current. More emergently, you've found a lump in your breast. So, can you have a mammogram when pregnant? The answer is yes, but there are several things to consider.

Pregnancy creates substantial hormonal changes that affect the body, as well as breast tissue. Estrogen and progesterone's rise causes the breasts to expand and condition to produce milk, which results in denser tissue. This increased density is more challenging to detect any abnormalities with using mammograms. Even post-delivery, should the woman be breastfeeding, milk-filled glands can also make the breasts denser and, as a result, make mammogram readings less clear.

While 3D mammograms have improved imaging technology to help navigate dense breast tissue, doctors often suggest postponing routine screening mammograms until after pregnancy if there are no symptoms or high-risk factors. However, if a lump or abnormality is found, your doctor may recommend immediate diagnostic imaging.

When Is a Mammogram Necessary During Pregnancy?

Mammograms are not done routinely if a woman becomes pregnant, yet there are specific situations where one might be unavoidable. Breast cancer in pregnancy does occur—1 in 3,000 times—but it's not common. If a lump is detected by a woman, she has constant breast pain and no explanation, or she is at high risk (e.g., strong history of breast cancer in her family or genetic defect such as BRCA1 or BRCA2), a physician will order a mammogram.

The process itself takes very little radiation exposure. The radiation employed by a mammogram is concentrated on the breast, and there is little to no radiation that reaches other areas of the body. A lead apron is also placed over the belly to shield the unborn child.

Alternative Breast Imaging Options During Pregnancy

For pregnant women requiring breast imaging, physicians may initially suggest an ultrasound. In contrast to a mammogram, an ultrasound is not done with the use of radiation and is deemed safe for pregnant women.

An ultrasound of the breast can establish whether a lump is a fluid-filled cyst or a solid tumor that needs further investigation. Yet ultrasounds are not always diagnostic, and in certain instances, a mammogram or biopsy is needed to determine or rule out cancer.

Magnetic Resonance Imaging (MRI) is also an imaging choice but has some drawbacks. The majority of breast MRIs employ a contrast material called gadolinium, which is able to pass through the placenta and to the fetus. Although risks are not entirely clear, physicians usually do not use MRI with contrast unless necessary. Some practitioners may offer an MRI without contrast as an option.

What If You Find a Lump In Your Breast During Pregnancy?

Breast changes throughout pregnancy are normal, but finding a lump should never be taken lightly. If you notice a lump, alert your medical provider right away. They will conduct a clinical breast exam and potentially have you get an imaging study such as an ultrasound or mammogram to see whether anything needs to be done.

If imaging indicates a suspicious mass, a biopsy can be suggested. Core needle biopsy is the most frequently used and is safe during pregnancy. It consists of numbing the skin with local anesthetic and inserting a hollow needle into the area to obtain a small sample of tissue to be tested.

Breast Cancer Treatment During Pregnancy

In the extremely uncommon event of a diagnosis of breast cancer while pregnant, therapy will be determined by the nature and extent of cancer and by how far along in pregnancy one is. The most frequent form of treatment is surgery—either mastectomy (surgical removal of the entire breast) or lumpectomy (surgical removal of the lump)—which is usually safe while pregnant.

Chemotherapy is also possible but usually only attempted after the first trimester, when it can damage developing fetal tissue. Radiation therapy is not used during pregnancy and is typically deferred until after giving birth. Hormonal therapy and targeted therapies are also omitted until after giving birth.

Can I Get a Mammogram While Breastfeeding?

Yes, you can have a mammogram while you are breastfeeding. The radiation in a mammogram does not impact breast milk or hurt the baby. But breast density is still high during lactation, and this might complicate detection of abnormalities. To enhance image quality, physicians usually advise breastfeeding or pumping 30 minutes prior to the mammogram.

Routine screening mammograms are usually delayed in pregnancy unless there is a high-level concern.

If a lump is detected, an ultrasound is typically the initial imaging study done, with a mammogram being a consideration if additional assessment is necessary.

  • Pregnancy mammograms utilize minimal radiation and are safe when required.
  • Breast MRI with contrast is usually avoided in pregnancy.
  • Breast biopsy, when necessary, is safe during pregnancy.

If breast cancer does develop during pregnancy, there are available treatment options that can be adjusted to keep the mother and infant safe.

Pregnancy is a period of significant change, and health issues particularly those involving breast health, are anxiety-provoking. Routine mammograms are typically postponed until after giving birth, but diagnostic testing can be done if necessary. The best you can do is discuss changes you notice in your breasts with your healthcare provider in an open manner. Early detection and prompt treatment can make a very big difference in the health of both mother and fetus.

Nipah Virus Outbreak India: How Contagious Is It And Who Is Most At Risk?

Updated Jan 25, 2026 | 07:00 PM IST

SummaryNipah virus cases in West Bengal have raised concerns. Here’s what the virus is, how contagious it is, where it spreads, key symptoms to watch for, and how to stay safe.

Indian health authorities are moving quickly to control a Nipah virus outbreak after five confirmed cases and the quarantine of nearly 100 people in West Bengal. Officials said three fresh infections were detected earlier this week, adding to two earlier cases involving a male and a female nurse. Both nurses were employed at a private hospital in Barasat, close to Kolkata. According to Press Trust of India, the newly confirmed patients include a doctor, a nurse, and another healthcare worker.

Nipah Virus Outbreak India: What Is Nipah Virus?

Nipah virus (NiV) is a zoonotic infection, meaning it can spread from animals to humans. Fruit bats, also known as flying foxes, are the primary carriers, but the virus can also be transmitted through pigs and other animals such as goats, horses, dogs, or cats. According to the Cleveland Clinic, infection can occur when:

  • People or animals come into contact with bodily fluids like blood, urine, stool, or saliva from an infected animal.
  • People consume food items contaminated by infected animals.
  • People have close contact with someone infected with Nipah virus, most often while providing care.

The most effective way to reduce the risk of Nipah virus is to avoid contact with sick animals, particularly bats and pigs, in regions where outbreaks have been reported. It is also advised to stay away from foods that animals could contaminate, such as raw date palm sap or partially eaten fruit. Since Nipah can spread between people through bodily fluids, caution is essential when interacting with infected individuals.

Nipah virus can lead to symptoms ranging from mild illness to severe disease, including encephalitis, which can be fatal. At present, there is no specific drug or vaccine available, and treatment focuses on managing symptoms and providing supportive care.

Preventing Nipah virus relies on strict infection control practices, including the use of protective gear, proper surface disinfection, and avoiding areas or animals linked to known outbreaks.

Nipah Virus Outbreak India: Where Is Nipah Virus Found?

Nipah virus outbreaks are reported almost every year in parts of Asia, mainly in Bangladesh and India. The virus was first identified in 1999 during an outbreak in Malaysia and Singapore that caused around 100 deaths. To stop the spread, more than one million pigs were culled, resulting in significant economic losses. Since then, roughly 20 outbreaks have been recorded.

People traveling to countries prone to Nipah outbreaks, such as Bangladesh, Malaysia, Singapore, or India, are advised to take extra precautions. Other regions, including Cambodia, Indonesia, Madagascar, the Philippines, and Thailand, may also be at risk because the bat species responsible for spreading the virus are present there.

Nipah Virus Symptoms and Causes

Early signs of Nipah virus infection may include:

  • Fever
  • Headache
  • Difficulty breathing
  • Cough and sore throat
  • Diarrhea
  • Vomiting
  • Muscle aches and extreme weakness

Symptoms usually appear within four to 14 days after exposure. Many people first experience fever or headache, followed by breathing problems such as cough or shortness of breath.

In more serious cases, the infection can progress to encephalitis, a dangerous brain inflammation. Severe symptoms may include:

  • Confusion or altered mental state
  • Slurred speech
  • Seizures
  • Coma
  • Severe breathing distress

Experts do not fully understand why some people develop serious illness while others experience mild or no symptoms at all.

Nipah Virus: How Contagious Is It?

Nipah virus is infectious and can spread from animals like bats and pigs to humans through bodily fluids or contaminated food. It can also pass between people through close contact, especially in caregiving settings. While it can spread via respiratory droplets in enclosed spaces, it is not considered highly airborne and usually requires close, prolonged contact for transmission. Common routes include direct exposure to infected animals or their fluids, consuming contaminated fruits or date palm sap, and contact with bodily fluids such as saliva, urine, or blood from an infected person.

Nipah Virus Outbreak India: Who Is Most At Risk?

People most at risk of Nipah virus are those who are more likely to come into close contact with infected animals or patients. This includes:

  • Healthcare workers caring for Nipah patients, especially without proper protective equipment
  • Family members and caregivers who have close physical contact with infected individuals
  • People living near bat habitats, particularly fruit bat roosting areas
  • Those who consume contaminated food, such as raw date palm sap or fruits partially eaten by bats
  • Farmers, animal handlers, and slaughterhouse workers who work with pigs or other animals that can carry the virus
  • Residents of outbreak-prone regions in India and Bangladesh, where Nipah cases recur
  • People with weak immunity, who may develop more severe illness after infection
  • Close, prolonged contact is the biggest risk factor. Casual contact in public spaces is far less likely to spread the virus.

Ammonia Surge Triggers Delhi Water Crisis: How To Detect Contamination And Stay Safe

Updated Jan 25, 2026 | 05:00 PM IST

SummaryHigh ammonia levels in Delhi’s water supply have triggered a citywide crisis. Learn the health risks, how to detect ammonia in water at home, and key safety precautions.

High ammonia levels in the Yamuna, along with reduced water supply from Haryana via the Munak Canal, have triggered a water shortage across several parts of Delhi. Seven out of the city’s nine water treatment plants have been impacted. Delhi’s largest facility at Wazirabad, which normally supplies around 140 MGD (million gallons per day), has been shut down entirely. Meanwhile, the Chandrawal plant is operating at only half its capacity and is supplying close to 100 MGD to the capital.

Delhi Water Crisis

Localities facing disruptions include IGI Airport, Dwarka, Shalimar Bagh, Sultanpuri, Raja Garden, Rajouri Garden, Karala, Bawana, Prashant Vihar, Madhu Vihar, Mangolpuri, Paschim Vihar, Mayapuri, Janakpuri, and nearby areas. In a statement, the Delhi Jal Board (DJB) said, “To make up for the diversion, Haryana is supplying water to DJB. Residents are advised to use water carefully during this period.” Officials have indicated that the water crisis could persist until February 4, 2026.

What Happens When Water Has High Ammonia Content?

Elevated ammonia levels in drinking water can pose serious health concerns, especially when concentrations cross safe limits such as 0.5 ppm (parts per million). Here’s how excess ammonia can affect the body.

1. Respiratory Issues

Ammonia can irritate the airways, leading to symptoms like coughing, a runny nose, chest discomfort, and difficulty breathing if consumed or inhaled from contaminated water. People with asthma or existing lung conditions may experience aggravated bronchitis or face a higher risk of pneumonia.

2. Neurological Effects

Ammonia acts as a neurotoxin and can enter the bloodstream, interfering with normal brain function. This may result in headaches, dizziness, confusion, or trouble concentrating. In cases of heavy exposure, it can cause nausea, vomiting, or poisoning accompanied by breathing distress.

3. Organ Damage

Long-term exposure to ammonia can strain the kidneys by increasing their workload, which may eventually impair function. It can also raise nitrite and nitrate levels in the body, increasing the risk of vascular problems, and has been linked to reproductive concerns such as infertility or low birth weight.

4. Skin and Eye Irritation

Direct contact with water containing high ammonia can irritate the skin, eyes, and mucous membranes, sometimes causing rashes or conjunctivitis. Children, pregnant women, and older adults are especially vulnerable and should be extra cautious.

How To Check For Ammonia In Water At Home?

There are a few simple ways to identify possible ammonia contamination at home without laboratory testing.

Indicators

Ammonia gives off a sharp, pungent smell often compared to fish or household cleaning agents, which can be noticeable even at low levels of 0.5–1 mg/L. The water may also taste bitter, earthy, or moldy. If you notice these signs, avoid using the water. Checking the pH can also help, as ammonia can push pH below 7, making the water more acidic. pH test strips are an easy option for this.

Chlorine Residual Test

When ammonia reacts with chlorine, it forms chloramines, which lowers free chlorine levels to below 0.4 mg/L. You can test tap water using pool test strips or chlorine kits. Low readings may point to the presence of ammonia and serve as a useful indirect indicator in treated water supplies.

Safety Tips And Precautions

If you live in an area at risk of ammonia contamination, taking precautions is essential to reduce health issues such as irritation, nausea, or neurological symptoms. Here are some practical steps to follow.

1. Use Certified Filtration

Install reverse osmosis (RO) or activated carbon filters that are certified to remove ammonia and chemical contaminants, such as those meeting NSF/ANSI 58 standards. These systems are effective at trapping ammonia ions, unlike basic filters, and make drinking water safer for daily use.

2. Avoid Boiling Alone

While boiling kills bacteria, it can cause ammonia to vaporise, concentrating it in the remaining water and steam. Avoid inhaling the vapours or relying on boiling alone. If boiling is unavoidable, combine it with proper filtration or allow the water to cool uncovered in a well-ventilated space so gases can dissipate before storage.

3. Safe Handling

Always test water if contamination is suspected. In case of exposure, rinse skin or eyes with lukewarm water for 15–30 minutes and seek medical attention if there are burns or if the water has been ingested. Keep ammonia-based cleaning products away from food preparation areas and out of children’s reach to prevent accidental mixing or exposure.

Double Covid Surging Across UK, Doctor Urges Immediate Vaccination

Updated Jan 25, 2026 | 01:00 PM IST

Summary Doctor warns of “double Covid” as UK cases rise, explaining how people can be reinfected while still unwell, the latest symptoms to watch for, and who should get the Covid vaccine now.

A GP has warned that people can catch Covid more than once in a short span, including while they are still unwell from a previous infection. In some cases, this may even involve picking up two strains of the virus at the same time, a situation doctors are calling “double Covid”.

Doctor Warns of ‘Double Covid’ as UK Cases Rise

New figures from the UK Health Security Agency show confirmed Covid cases have risen by 11 per cent. In the week leading up to January 9, 51 deaths were recorded and more than 500 people were in hospital with the virus.

Can You Catch Covid Twice at the Same Time?

Speaking to the BBC, GP Dr Nish Manek said it is possible to be infected again while still dealing with ongoing symptoms, including long Covid. She explained that having long Covid does not provide immunity against reinfection.

According to Dr Manek, protection from a previous infection or vaccination reduces over time. New variants are also better at evading the immune system, making repeat infections more likely.

Why Long Covid Does Not Protect You

Dr Manek said immunity can fade within months, leaving people vulnerable. New strains of the virus, including recent Omicron-related variants circulating in 2025, are able to bypass existing immune defences.

As a result, someone managing long Covid symptoms may still catch Covid again. A fresh infection can trigger a relapse of symptoms or slow down recovery.

She added that a positive test may reflect either the same strain or a new variant. In both cases, it is still Covid and should be taken seriously.

Vaccines Still Reduce Severe Illness

Dr Manek stressed that vaccination remains important. While vaccines may not fully prevent infection, they significantly reduce the risk of severe illness and hospitalisation.

She said Covid continues to change and remains present in the community. Simple protective steps still matter, including testing when unwell, wearing masks in crowded indoor settings, and staying up to date with vaccinations.

Which Covid Variants Are Circulating Now

As of January 2026, Covid continues to evolve in the UK. One of the most common strains currently in circulation is NB.1.8.1, often referred to as the Nimbus variant.

Latest Covid Symptoms to Watch For

Doctors say symptoms linked to current variants often affect the upper respiratory tract and can feel similar to a bad cold or flu.

Commonly reported symptoms include a very painful sore throat described as feeling like razor blades, a hoarse voice with swollen glands, blocked or runny nose, sneezing, and extreme tiredness. Fever, a persistent cough, and body aches are still widely seen.

Loss of taste or smell is now reported far less often than during the early stages of the pandemic.

Who Is Eligible for a Covid Vaccine in the UK

The UK has moved to a targeted vaccination approach, focusing on those most at risk of serious illness.

The current winter vaccination programme is coming to an end. The final date to receive this dose is January 31, 2026. You are eligible if you are aged 75 or over, live in a care home for older adults, or are aged six months or older and immunosuppressed due to medical treatment or long-term conditions.

A spring booster programme has been confirmed for 2026. Appointments are expected to open in late March, with vaccinations starting from April 13. Eligibility criteria remain the same as the winter programme.

How To Book Your Covid Vaccine?

Eligible individuals do not need to wait for an invitation. Vaccinations can be booked online through the NHS website, via the NHS App, by calling 119 for free, or by visiting a walk-in pharmacy or clinic.

Doctors continue to urge those eligible to get vaccinated while doses are still available.
