Cancer is a large group of diseases that can start in almost any organ or tissue of the body when abnormal cells grow uncontrollably, and go beyond their usual boundaries to invade adjoining parts of the body. According to the World Health Organization (WHO), it is the second most common cause of death globally, accounting for millions of deaths every year. Lung, prostate, colorectal, stomach and liver cancer are the most common types of cancer in men, while breast, colorectal, lung, cervical and thyroid cancer are the most common among women. However, these are not necessarily the deadliest forms of cancer.

What makes cancer the deadliest depends upon how many people have it and what percentage of those people actually survive. Cancer researchers determine this on the basis of five-year relative survival. This is the percentage of people who are expected to survive the effects of a given cancer, excluding their risk of other possible causes of death, for five years past a diagnosis. It is also important to note that what makes cancer really deadly is that practically no cure for it. A cure for cancer would imply that there are no cancerous cells remaining in the body.

Here are the 5 deadliest cancers in the U.S., according to SEER five-year relative survival data for cases diagnosed between 2014 and 2020.

1. Pancreatic cancer occurs when cells in your pancreas, a gland in your abdomen that aids digestion, mutate and multiply out of control, forming a tumour. Major risk factors include smoking, obesity, diabetes, chronic pancreatitis, certain genetic mutations and environmental chemical exposure.

2. Esophageal cancer develops in the oesophagus, which is the tube that connects your throat to your stomach.

3. Liver cancer and intrahepatic bile duct cancer originate in the liver or bile ducts, often linked to hepatitis infections, heavy alcohol use, obesity, and aflatoxin exposure.

4. Lung and bronchus cancer primarily caused by smoking, secondhand smoke, and environmental pollutants, affects the lungs and airways, making it the leading cause of cancer death in the US.

5. Acute myeloid leukaemia (AML) is an aggressive blood and bone marrow cancer that progresses rapidly, often linked to genetic mutations, radiation exposure, and certain chemicals.

Millions of Americans rely on cetirizine, the generic version of Zyrtec, to keep seasonal allergies at bay. But a recent nationwide recall has raised concerns after some tablets were found to be contaminated with another medication, prompting FDA to warn consumers to check their medicine bottles.

The US Food and Drug Administration (FDA) has announced that India-based company Unique Pharmaceutical Laboratories, a division of J.B. Chemicals & Pharmaceuticals Ltd., is voluntarily recalling four lots of Cetirizine Hydrochloride Tablets USP 5 mg because of potential cross-contamination with ranitidine, a medication used to treat heartburn and stomach ulcers.

Why Was The Allergy Medicine Recalled?

According to the FDA, the recall was initiated after a pharmacy technician noticed unusual tablets. Some cetirizine tablets had red dots or discoloration, which led to a proper investigation. The company later confirmed that certain tablets had been cross-contaminated with ranitidine during manufacturing.

The FDA, in its recall announcement, said, "Unique Pharmaceutical Laboratories is voluntarily recalling four lots of Cetirizine Hydrochloride Tablets USP 5 mg to the consumer level due to cross contamination with Ranitidine."

Although no adverse events have been reported so far, the company is recalling the medication as a precaution because taking an unintended drug could pose health risks for certain patients.

Why Is Cross-Contamination A Grave Concern?

Cross-contamination occurs when traces of one medication accidentally end up in another drug during manufacturing or packaging.

In this case, people expecting to take an allergy medicine could unknowingly consume ranitidine which could lead to adverse effects.

While ranitidine was once commonly used to treat acid reflux and heartburn. The medication decreases the amount of acid made in the stomach, according to MedlinePlus and the U.S. National Library of Medicine.

The accidental exposure is particularly concerning for people who are hypersensitive to ranitidine or its ingredients.

According to the FDA, these individuals could experience reactions ranging from mild allergic symptoms to potentially life-threatening conditions.

Although Unique Pharmaceutical Laboratories said it has not received any reports of adverse reactions related to the recalled tablets, the contamination could pose a serious risk for people who are allergic or hypersensitive to ranitidine.

According to the recall notice, individuals who unknowingly take the contaminated tablets could experience anaphylaxis, a severe and potentially life-threatening allergic reaction that requires immediate medical attention. Symptoms of anaphylaxis may include:

• Difficulty swallowing
• Loss of consciousness
• Hypotension (low blood pressure)
• Dyspnea (shortness of breath)
• Angioedema (sudden swelling beneath the skin)
• Swelling of the throat or face
• Pruritus (itching)
• Urticaria (hives)

What Should You Do If You Have The Recalled Medication?

Consumers who have the affected cetirizine tablets should stop using the product and check whether their bottle belongs to one of the recalled lots. Anyone who develops symptoms like swelling of the face or throat, difficulty breathing or swallowing, hives, or dizziness after taking the medication should seek immediate medical attention.

The United Nations has warned that health workers responding to the rapidly expanding Ebola outbreak in the Democratic Republic of the Congo (DRC) are facing growing risks as the virus has infected new areas, prompting urgent calls for stronger infection control measures, funding and global support.

The warning comes as the World Health Organization (WHO) reported that the outbreak has become one of the largest ever recorded in the country, with more than 2,400 confirmed Ebola cases and nearly 1,000 deaths. WHO said the outbreak continues to expand despite intensive response efforts.

According to WHO, the epidemic is being caused by the Bundibugyo ebolavirus, a strain for which there is currently no approved vaccine or specific treatment, making containment and treatment even more challenging.

UN Warns Frontline Responders

The UN and its agencies have expressed concern that healthcare workers remain among the most vulnerable because they are in direct contact with infected patients and often work in unsafe environments conditions.

"Health workers are on the front line of this response and must be protected through adequate infection prevention measures, personal protective equipment, training and support," WHO officials have stressed as response teams continue to battle the outbreak.

On Monday, the UN warned on Monday that Ebola could spread in displacement camps in eastern Democratic Republic of Congo, adding that overcrowding could increase transmission and new cases.

The UN aid agency OCHA said that confirmed Ebola cases had been reported in "at least 16 displacement sites" across Ituri, the epicentre of outbreak.

"These sites host more than 270,000 displaced people, with overcrowding and limited access to basic services increasing the risk of disease transmission," OCHA said in a statement.

Separately, the UN's International Organization for Migration (IOM) warned that the movement of Ebola victims' bodies between different regions is increasing the risk of transmission, especially in communities where traditional burial practices involve close contact with the deceased.

"Transporting bodies over long distances creates additional opportunities for the virus to spread," the UN agency warned, urging safer burial practices.

Ebola Outbreak In DRC Expanding Faster Than Response

According to the World Health Organization, there have been 2,344 confirmed cases of Ebola in the DRC and at least 930 deaths.

More than 460 patients have recovered, while there are 192 suspected cases.

Marking the 17th outbreak, the current Ebola epidemic was declared on May 15 after several deaths were reported in Ituri.

WHO has warned that the outbreak is expanding faster than the response efforts, with transmission now occurring across multiple provinces. The agency said that even though some affected areas are starting to see stability, several hotspots continue to report persistent transmission and new cases.

"We are tailoring our response according to different transmission patterns," WHO officials said, noting that surveillance, contact tracing and treatment capacity continue to be expanded.

Health authorities are also increasingly concerned about infections with unknown transmission chains, suggesting that some cases are being detected too late for effective contact tracing.

Status Of Ebola Outbreak In Uganda

In neighboring Uganda, officials have reported encouraging progress. The country has discharged its last Ebola patient and has entered the WHO-required 42-day countdown before it can officially declare the outbreak over, provided no new infections are detected.

Uganda has recorded 20 confirmed Ebola cases, most linked to cross-border transmission from the DRC, and has not reported a new case since late June.

WHO, the UN and African health authorities continue to call for increased international funding, rapid deployment of medical teams and stronger protection for frontline healthcare workers.

A total of 52,10,302 girls across India have received the Human Papillomavirus (HPV) vaccine under the nationwide campaign launched by Prime Minister Narendra Modi in February, the government informed Parliament during the ongoing Monsoon Session.

The nationwide vaccination campaign for 14-year-old girls was launched from Rajasthan's Ajmer as part of India's efforts to eliminate cervical cancer.

“The nationwide HPV vaccination campaign was launched on February 28, for approximately 1.2 crore eligible beneficiary girls aged 14 years across all 36 States and Union Territories. As of July 15, a total of 52,10,302 girls have received the HPV vaccine across the country,” Union Minister of State for Health and Family Welfare Anupriya Patel said in a written reply in the Rajya Sabha.

The Minister said the HPV vaccine is being provided free of cost at designated government health facilities, including:

• Ayushman Arogya Mandirs–Primary Health Centers (PHCs)

• Community Health Centers (CHCs)

• Sub-District Hospitals (SDHs) and District Hospitals (DHs)

• Government Medical Colleges (GMCs)

She also said the government's cervical cancer prevention strategy includes HPV vaccination, screening, early diagnosis at Ayushman Arogya Mandirs (AAMs), and treatment through Day Care Cancer Centers (DCCCs).

Immunization Coverage Remains Above 90%

The Minister also updated Parliament on India's immunization program.

“As per the National Health Policy 2017 goals, the National Full Immunization Coverage has been maintained more than 90% for the last four years,” Patel said. National full immunization coverage was:

• 94.7% in 2022–23

• 93.7% in 2023–24

• 98.3% in 2024–25

• 97.9% in 2025–26

Patel also said that the government has taken several steps to improve preparedness for future pandemics and public health emergencies, including:

• Launch of the Pradhan Mantri-Ayushman Bharat Health Infrastructure Mission (PM-ABHIM) to strengthen public health infrastructure, disease surveillance, diagnostics, research, and emergency response.

• Strengthening the Integrated Disease Surveillance Program (IDSP) with trained multidisciplinary Rapid Response Teams (RRTs).

• Expansion of the Indian Council of Medical Research's Virus Research and Diagnostic Laboratory (VRDL) network to more than 160 laboratories for pathogen diagnosis.

Meanwhile, the Nationwide Viral Research and Diagnostic Laboratories (VRDL) network under ICMR has been expanded to 163 laboratories, comprising 11 Regional VRDLs, 27 State VRDLs and 125 Medical College VRDLs, to strengthen diagnostic capacity across the country.

Cervical Cancer Cases Decline

Meanwhile, recent data from the ICMR's National Cancer Registry Program (NCRP) show that India has recorded a significant decline in its cervical cancer burden.

According to the latest estimates, new cervical cancer cases have fallen by 37% over the past decade, declining from about 1.27 lakh cases annually to around 79,000, marking a major public health milestone in the fight against one of the country's most common cancers among women.

Unlike many other cancers, cervical cancer is considered highly preventable through HPV vaccination, regular screening, and timely treatment of precancerous lesions.

The WHO global targets for 2030 include vaccinating 90 percent of girls by age 15, screening 70 percent of women by ages 35 and 45, and ensuring 90 percent of women with pre-cancer and invasive cancer receive appropriate treatment.
