SummaryAs and when people age, their blood and other cells naturally develop mutations and some of them can also increase the risk of cancer. When anyone donates blood, his or her body compensates by producing new blood cells, which can influence the genetic diversity of stem cells in the bone marrow.

A recent study suggests that people who donate blood regularly may have genetic changes in their blood that could in fact reduce the risk of developing cancer. It is conducted by the researchers at the Francis Crick Institute, and the study has now provided new insights into how and why blood cancers develop. The study is published in the journal Blood and was conducted by the scientists from Heidelberg and the German Red Cross blood donation center. There is yet a need for further research to confirm these findings.

What Did The Study Find?

The researchers examined the blood of two groups of healthy male donors in their 60s:

  • One group had donated blood three times a year for 40 years.
  • The other group had donated only about five times in total.

The goal was to analyze genetic mutations in their blood and assess whether frequent donation had any impact on their genetic makeup.

How Can Blood Donation Affect Stem Cells?

As and when people age, their blood and other cells naturally develop mutations and some of them can also increase the risk of cancer. When anyone donates blood, his or her body compensates by producing new blood cells, which can influence the genetic diversity of stem cells in the bone marrow. The study also found that both groups had a similar number of mutations. For instance the frequent donors had 217 mutations, while the irregular donors had 212 mutations.

However, the nature of these mutations differed. In the frequent donors, 50% of the mutations were of a type not associated with a high risk of blood cancers, compared to only 30% in the irregular donors.

Further laboratory analysis showed that these specific mutations behaved differently from those linked to leukemia, a type of blood cancer. When human blood stem cells with these mutations were injected into mice, they were found to be highly effective at producing red blood cells, which is considered a positive outcome.

Dr. Hector Huerga Encabo, one of the study authors, emphasized that these mutations do not indicate an increased risk of leukemia. The findings suggest that regular blood donation may influence how stem cells evolve, but whether this translates into a lower cancer risk remains uncertain.

Limitations

One notable disadvantage is the "healthy-donor effect"—because blood donors are often healthier than the general population, their lower cancer risk could be unrelated to blood donation.

Dominique Bonnet, senior researcher and head of a stem-cell laboratory at the Francis Crick Institute, stressed the need for larger studies with female volunteers to confirm the findings.

Despite ongoing research into potential health benefits for donors, the primary goal of blood donation remains saving lives. NHS Blood and Transplant emphasized that while the study is interesting, further research is required to draw firm conclusions. The organization also noted that blood supplies are currently critically low and encouraged eligible individuals to donate.

Late Joe Thompson’s Wife Pregnant Via Frozen Embryo: How Egg Freezing Works

Updated Apr 9, 2026 | 11:01 AM IST

Summary​While egg freezing is possible at various stages of life, experts recommend doing it at an optimal age -- in the late 20s or early 30s when the eggs are of higher quality-- for better outcomes.

Continuing the legacy of football legend Joe Thompson, his wife Chantelle revealed she is pregnant with his baby after IVF treatment using frozen embryos.

Joe Thompson died in 2025 after developing cancer for a third time - beating the illness twice.

But after the former Manchester United star was diagnosed with Hodgkin Lymphoma for a third time, which had spread to his lungs, he died aged 36.

"It just means absolutely everything. I know it's never going to replace Joe obviously. Joe's Joe. But to be able to bring his baby into the world again is beautiful," Chantelle said.

She said Joe had two visions of their family with a baby boy before he died, and he even gave her the name for the baby boy he predicted, and she got pregnant on her first attempt of IVF after he had died.

How Egg Freezing Works

Egg freezing, also known as oocyte cryopreservation, is an option that has gained significant traction in recent years. It offers women the ability to pause their biological clock and preserve the possibility of having children in the future.

Egg freezing takes a woman's unfertilized eggs from her ovaries and stores them at sub-zero temperatures to be utilized later. It is made to enable women to keep their fertility intact, especially if they are not yet ready to have a baby.

Dr. Pavithra M, Obstetrician, Gynecologist, and Infertility Specialist, told HealthandMe that the workup begins with hormone workup and evaluation of various parameters, such as age, body mass index (BMI), and ovarian reserve.

"On the second day of the menstrual cycle, baseline ultrasound scanning is performed to assess the number of follicles; thereafter, various tests of blood are conducted to assess hormone levels. If a woman's parameters are all normal, then she is administered hormonal injections for about 10-12 days."

It causes ovarian hyperstimulation and multiple mature eggs, monitored through ultrasound scans. A trigger shot is administered once the follicles have reached optimal size to help with final egg maturation. It takes 34-35 hours from the trigger shot, wherein eggs are retrieved by minimally invasive procedures under general anesthesia.

"Using a transvaginal ultrasound probe with a needle, each follicle is punctured, and the follicular fluid is aspirated. The retrieved eggs are then screened for quality before undergoing vitrification—a rapid freezing technique that minimizes ice crystal formation and cellular damage," Dr. Pavithra added. The eggs are then stored in liquid nitrogen tanks for long-term preservation.

While egg freezing is possible at various stages of life, experts recommend doing it at an optimal age -- in the late 20s or early 30s when the eggs are of higher quality-- for better outcomes.

Annabelle Gurwitch, an American author, actress, and television host, has opened up about her lung cancer diagnosis in her new memoir.

In her sixth book, ‘The End of My Life Is Killing Me’, Annabelle Gurwitch offers a satirical take on her journey with stage 4 lung cancer. The best-selling author found out about her cancer status in 2020, when she went for a COVID-19 test.

In the book, Annabelle Gurwitch writes about her life as a "cancer slacker", her divorce, treatment with a targeted therapy that turns off the gene that has gone rogue, radiation, and chemotherapy, all with a humorous take.

Lung Cancer: A Stealthy Disease, Says Annabelle Gurwitch

Notably, the American actress had no symptoms and was not a smoker. She went to get her “persistent little cough” tested for COVID, when a doctor told her that there was something suspicious on her lungs.

Soon after, an X-ray and a biopsy confirmed her diagnosis of stage 4 cancer.

Annabelle Gurwitch called lung cancer a “stealthy disease" as, other than her little cough, she exercised every day and felt like she was in really good health.

“You know, you can be asymptomatic with Stage 4 lung cancer because lung cancer is a really stealthy disease, and this is why it's such a big killer, still the No. 1 cause of cancer deaths, because some lung cancers, like the one I have, are not recognized by the immune system," Annabelle Gurwitch told NPR.

"So my body didn't know that it was - anything was happening, which is, I mean, I was going to regular doctor's appointments. And this is why it's often diagnosed at a late stage, and such a big killer because it's not diagnosed at an earlier stage,” she added.

Can Non-Smokers Get Lung Cancer?

Contrary to long-held assumptions, a significant proportion of lung cancer cases now occur in people with no history of smoking. The American Cancer Society reports that approximately 10-20 percent of lung cancers in the U.S are found in non-smokers, often attributed to genetic mutations like EGFR, environmental exposures, or radon gas.

These cases are more common in women, younger adults, and individuals of East Asian descent, but they can affect anyone.

Early Signs and Symptoms to Look Out For

Lung cancer symptoms can mimic less serious conditions, which is why they’re often dismissed or misdiagnosed. If you experience the following symptoms persistently, don’t ignore them—regardless of your age or smoking history:

  • Chest pain or discomfort
  • Unexplained shortness of breath
  • Persistent cough or wheezing
  • Shoulder, back, or rib pain
  • Fatigue or sudden weight loss
  • Blood in sputum (though not always present).

Doctors Share Preventable Risk Factors That Can Land You in the Emergency Ward

SummaryIgnoring symptoms like a persistent stomachache or a nagging cough can allow a condition to worsen over time, eventually leading to an emergency.

A visit to the emergency ward (ER) of a hospital can definitely feel scary, and you want every reason to avoid ending up there as a patient. From broken bones to life-threatening emergencies, it’s a place filled with urgency, uncertainty, and intense emotions. Imagine what doctors and other health workers face every day.

However, while many cases are unavoidable, there are several that can be completely prevented, said doctors, while sharing a few. These include:

  • Symptoms ignored for long
From persistent pain to unusual fatigue to breathlessness, to unexplained weight loss, many people silently face these and tend to overlook. For some of its fear, for others it may be responsibilities.

However, ignoring symptoms like a persistent stomachache or a nagging cough can allow a condition to worsen over time, eventually leading to an emergency.

“People say, ‘It’s pretty mild. I’m not worried about it,’” Dr. Evelyn Huang, an emergency-room physician with Orlando Health, was quoted as saying to Time.

“Days become weeks, weeks become months, and months can even become years, and by the time they're seeing me, these things have progressed so far that they’re now something dangerous.”

Seeking timely medical advice and not delaying checkups can help prevent complications and avoid unnecessary ER visits, the expert said.

  • Drowning
It is the leading cause of death in children ages 1 through 4—and one of the most preventable.

Dr. Cheyenne Falat, assistant medical director of the adult emergency department at University of Maryland Medical Center stated that every time a patient comes ER with a drowning case, he hears the same story.

“I would have been watching them, but I thought the babysitter was watching them. I thought my spouse was watching them. I thought their grandparents were watching them.”

The doctor recommended instead starting swimming lessons as early as possible. She also urged for fences with childproof gates near pools.

  • Falling
Another common reason to end up in ER includes falling off ladders, resulting in fractures, deep cuts, or head injuries.

  • Frostbite and hypothermia
Cold injuries like frostbite (when body tissues actually freeze) and hypothermia (a dangerous drop in core body temperature that can slow, and eventually stop, the body’s vital functions) can also create medical emergencies.

People often don’t realize how quickly conditions can turn.

“They think, ‘I won’t be at risk for hypothermia because it's a little warmer during the day,’” said Falat. “Then they sweat,” which can leave their clothing damp and their bodies more vulnerable once temperatures drop.

Heat-related illnesses include mild dehydration to heat exhaustion and, in the most extreme cases, heat stroke, which can be deadly.

  • Choking during sex
Dr. Jeff Yoo, an emergency specialist, noted about injuries during consensual choking during sex, which researchers have recently described as "prevalent" among young people in the US, the report said.

Recently, for example, he treated a young woman who came to the ER with neck pain, a hoarse voice, and bruising; she assured Yoo that she had wanted her partner to choke her. “I’m not judging anyone who enjoys this, but it's way more dangerous than people think,” he said.

  • Party drug

A harmless party drug -- gamma-hydroxybutyric acid, or GHB -- can also turn life-threatening. It is a clear, odorless substance sometimes called “liquid ecstasy.”

While in small amounts, it can make people feel relaxed or euphoric, but when taken in overdose, it can lead to unconscious and breathing difficulties. “It’s one of the most awful sights,” Yoo said , adding that in severe cases, some patients need to be put on a ventilator to survive.
