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.

A treatment already popular in the US for skin care, pain relief, and faster healing may soon be known for something far more serious. A new study suggests red light therapy could help protect football players’ brains from chronic inflammation caused by repeated hits to the head.

Experts say the findings are early but promising, especially in the ongoing search for ways to reduce long term brain damage in contact sports.

What Is CTE?

Chronic traumatic encephalopathy, or CTE, is a degenerative brain disease linked to repeated head injuries. It is commonly found in former football players, boxers, and military personnel exposed to blast injuries. Over time, the condition can cause memory loss, confusion, mood changes, aggression, and eventually problems with movement, speech, swallowing, and breathing. There is currently no cure, and doctors still do not know how to slow its progression.

Why inflammation matters in CTE

For now, the only proven way to lower CTE risk is to reduce repeated brain trauma through better helmets, rule changes, and fewer hits to the head. But with more than 100 former NFL players diagnosed with CTE after death and many more suspected cases, experts agree that prevention tools alone are not enough.

Researchers believe chronic inflammation in the brain plays a major role in how CTE develops and worsens over time. If that inflammation can be reduced early, it could potentially limit long term damage.

Red light therapy, also known as photobiomodulation, has already been shown to reduce inflammation in other parts of the body. It works by stimulating energy production inside cells and improving blood flow, which helps tissues repair and recover.

Inside the football study

To see whether the therapy could help the brain, researchers at the University of Utah Health studied 26 collegiate football players during a full season. Half received active red light therapy using a light emitting headset and a small device placed inside the nose. The other half used an identical looking device that did not emit light.

Players completed three 20 minute sessions each week over 16 weeks. Brain scans were taken before and after the season.

The results were striking. MRI scans showed that players in the placebo group experienced a significant increase in brain inflammation by the end of the season. In contrast, those using red light therapy showed little to no increase, with protection seen across most brain regions.

Why experts are paying attention

Specialists who reviewed the findings say the results align with what scientists already understand about inflammation and brain injury. Reducing the inflammatory response after repeated impacts could help limit the damage that builds up over time.

Another advantage is that the therapy is non invasive and does not involve medication. Most users report no major side effects, which makes it especially appealing for athletes.

That said, experts caution against buying over the counter red light devices. The therapy requires very specific wavelengths that can penetrate skin and tissue effectively. Many consumer products do not meet those standards.

Researchers stress that more studies are needed to confirm long term safety and effectiveness. A large Department of Defense funded trial is already planned, involving 300 people with persistent concussion or traumatic brain injury symptoms, including veterans and first responders.

If future research continues to show benefits without harm, red light therapy could one day become part of how teams protect athletes’ brains, not just in football, but across many sports.

Nicole "Snooki" Polizzi opened up about a cancer scare. Now, 38, the Jersey Shore star, posted on her TikTok an emotional video, where she explained that she has been dealing with abnormal pap smear results. She said that it has been about four year since the precancerous cells were found. Because of that she had to undergo an "uncomfortable" colposcopy and biopsy.

She said that when the results came back, the doctor informed her that her cervix is "Not looking great". The doctor had found cancerous cells on the top of her cervix. She said that she would soon need a cone biopsy under anesthesia for further testing. "I am terrified. It is scary, but we have to get it done because cervical cancer is nothing to joke about."

She said, "But whatever to keep me healthy and safe to be here for my kids that I have now," referring to her three children with her husband Jionni LaValle.

In her TikTok video, she said that she is scared and freaking out. She also said that she hopes to find community on social media with other women who have been through the same.

She also agreed to delaying her routine examination because of fear. "I waited on my appointments because I knew I might not get great results but also because I didn't want to feel the pain. I didn't want to deal with the stress of having to deal with all of this," she said.

Talking about her TikTok video, she said, “Just making this video to spread awareness to make sure you get your pap smears. And if your doctor calls you to do it again, do it, Make sure you are fine and prevent all the bad things that could happen, like cervical cancer." She said she was nervous but also shared that she received a lot of support from her friends and family. "Being a woman is not easy and is definitely a scary thing. I know I am going to be fine. It is just scary."

What Is Cervical Cancer?

Cervical cancer develops in a women's cervix (uterus opening) due to abnormal cell growth, primarily caused by persistent HPV infection, a common infection that's passed through sexual contact.

When exposed to HPV, the body's immune system typically prevents the virus from causing damage however, in a small percentage of people, the virus can survive for years and pave the way for some cervical cells to become cancerous.

Treatment involves surgery, radiation, and chemotherapy, with early detection significantly improving outcomes, though it remains a major cancer in low-income countries. Cervical cancer can also be prevented through vaccination and regular screening (Pap/HPV tests).

Dr Ninad Katdare told News18: "In its early stages, it is often more of a whisper than a shout. As a cancer surgeon who has treated hundreds of women with gynaecological cancers, I can say with confidence that recognizing these subtle cues can lead to earlier diagnosis and significantly better outcomes."

Nipah virus outbreak in India has led to nearly 100 people being quarantined. The first two cases identified in the eastern state of West Bengal in two nurses working in the private hospital in Barasat, near the state's capital Kolkata, has led to more testing. New cases, including a doctor, a nurse and a health staff member was confirmed and reported by the news wire agency PTI.

People with latest infections were admitted to the infectious disease hospital in Beleghata, whereas the earliest two people are still admitted in the Intensive Care Unit at a private hospital. Reports noted that the condition of the male nurse is improving, however, the woman nurse remains to be in a critical condition.

India is facing Nipah virus cases and contagion every year now. Experts are now cautioning people against the zoonotic nature of the viral infection. Rajeev Jayavedan, the former president of Indian Medical Association, Cochin, told The Independent, that infection among humans are rare and caused by the accidental spillover due to human-bat interface, which means consumption of fruits that may have been infected by bats. “This is more likely in rural and forest-adjacent areas where agricultural practices increase contact between humans and fruit bats searching for food,” he said.

Health and Me previously reported on how doctors are now advising people to be cautious while eating food. Speaking to TOI, Dr Aishwarya R, Consultant, Infectious Diseases at Aster RV Hospital advised people against eating certain food, including fruits fallen from trees, unpasteurized date palm sap and any other fruits without washing. The doctor explained that this infection can spread with infected animal who could bite fruits and spread the virus through their saliva.

Nipah Virus Tested In West Bengal Bats

A survey conducted on bats in West Bengal found no active Nipah virus infection. Though there were antibodies detected in one specimen, which indicated prior exposure. This was confirmed by a senior state forest department official on Tuesday. The survey was conducted amid the identification of two confirmed Nipah virus cases.

What Is Nipah Virus?

As per the World Health Organization (WHO), Nipah virus infection is a zoonotic illness that is transmitted to people from animals, and can also be transmitted through contaminated food or directly from person to person.

In infected people, it causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory illness and fatal encephalitis. The virus can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers.

Although Nipah virus has caused only a few known outbreaks in Asia, it infects a wide range of animals and causes severe disease and death in people.

During the first recognized outbreak in Malaysia, which also affected Singapore, most human infections resulted from direct contact with sick pigs or their contaminated tissues. Transmission is thought to have occurred via unprotected exposure to secretions from the pigs, or unprotected contact with the tissue of a sick animal.

In subsequent outbreaks in Bangladesh and India, consumption of fruits or fruit products (such as raw date palm juice) contaminated with urine or saliva from infected fruit bats was the most likely source of infection.

Human-to-human transmission of Nipah virus has also been reported among family and care givers of infected patients.
