Regular Blood Donation May Influence Cancer Risk

Updated Mar 12, 2025 | 11:00 PM IST

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.

Do You Sit Down To Put Your Socks On? Study Says This Could Mean You Are Getting Old

Updated Feb 18, 2026 | 12:00 PM IST

SummarySurvey of over-40s found everyday habits like groaning when bending, choosing quiet nights and sitting to wear socks signal ageing. Yet most feel happier, adopt healthier routines and view growing older as confidence awareness.

Are you still sitting down to put your sock on? A new study says that it may be an indicator that you are getting old. A research commissioned by American Pistachio Growers, partnered with British actor and comedian John Thomson, teamed up with nutritionist Rob Hobson to embrace aging positively. The research looked at common day-to-day signs of aging and found that 39 per cent of those surveyed (out of total 5,000 people over 40s) wanted a quiet drink over a night and they cared less about fashion. The research revealed that this could be an indicator that "you are creeping into the old category".

What Did The Study Find?

About one in three respondents (33 per cent) said they first felt they were no longer young when they caught themselves groaning while bending down.

Other telltale signs included discussing aches and pains with friends (30 per cent), preferring a quiet pub over a noisy bar (27 per cent) and naturally waking up at 6 am (12 per cent).

The survey also found people typically start feeling “not young” around 50, although 38 per cent believe old age now begins in the 80s rather than the 50s or 60s.

At the same time, 36 per cent said they have adopted habits to stay youthful, such as taking vitamins or supplements, choosing healthier snacks (19 per cent) and increasing protein intake (17 per cent).

"Getting older is inevitable, but you can still live life to the full. It is about embracing experience, having a laugh about the realities of aging and making small changes that actually make a difference. You don't need to overhaul your life, just make some healthy tweaks to your daily routine," said John.

Do You Feel Old?

Interestingly, only 36 per cent of people in the survey actually said they feel old. In fact, 27 per cent reported feeling more comfortable in their own skin now than when they were younger, and 18 per cent of those over 30 said they are more satisfied with life than they were in their thirties.

Lifestyle choices also seem to shift with age. Around 39 per cent now prioritize comfort over fashion, 34 per cent enjoy going for walks and 19 per cent have taken up gardening or DIY projects. Healthy eating becomes more intentional too, with 60 per cent of men and 61 per cent of women saying they are more health conscious than before.

Their motivations are practical: avoiding illness (59 per cent), staying active (58 per cent) and maintaining independence as they age (47 per cent).

TV nutritionist Rob Hobson, who partnered with American Pistachio Growers to promote the nut as an easy addition to a healthy routine, said ageing is less about decline and more about awareness. “Getting older isn’t about slowing down, it’s about making smarter choices,” he said. “Simple habits like eating nutrient-rich snacks, staying active and prioritizing sleep can help you feel youthful for longer. Age is just a number, but how you fuel your body makes all the difference.”

Suzanne Devereaux-McKinstrie, spokesperson for the non-profit organization, echoed the sentiment, saying later years can be empowering. “Getting older isn’t just about limitations, it’s about opportunities. It’s the perfect time to explore new hobbies, prioritise wellbeing and celebrate the confidence that comes with experience,” she said, adding that diet plays a key role in staying strong and active.

Why Indians Face Higher Fatty Liver Risk Than Europeans, Expert Explains

Updated Feb 17, 2026 | 03:58 PM IST

SummaryDr. Harsh Vyas reveals that genetics, superior nutrition, and consistent activity allow Europeans to process alcohol more efficiently. Conversely, many Indians face higher fatty liver risks even without drinking due to enzyme deficiencies, refined carbohydrate diets, and sedentary lifestyles that fail to protect the liver.

While it’s no secret that alcohol takes a toll on the body, particularly the liver, long-term health issues can arise even for light drinkers. This begs the question: how do Europeans seem to handle their booze so much better? Dr Harsh Vyas, a radiologist from Gujarat, recently tackled this on Instagram.

He compared two 37-year-old patients: an Italian who drinks regularly and an Indian teetotaler. Surprisingly, the Italian’s liver was in better shape than the Indian man’s, who was struggling with fatty liver disease despite never touching a drop of alcohol.

Here are some reasons he claims are the reason behind the massive difference between both men:

Genetic Efficiency

According to Dr. Vyas, the primary reason Europeans often appear to have a higher tolerance for alcohol than Indians is how their bodies process toxins at a molecular level.

Your body uses two main enzymes to break down alcohol. Think of them like a two-step cleaning crew which include Alcohol dehydrogenase (ADH) which converts alcohol into acetaldehyde, a highly toxic substance and Aldehyde dehydrogenase (ALDH) that converts that toxin into harmless acetic acid (vinegar), which the body can easily flush out.

In European livers, both enzymes usually work at peak efficiency. The toxic intermediate (acetaldehyde) is neutralized almost as fast as it is created. But in Asian populations, the activity of these enzymes is often lower. This means the toxic metabolites don't just pass through; they linger in the bloodstream for a much longer duration.

Because these toxins stay in the system of an Indian person longer, they cause more oxidative stress and inflammation. This explains why even a "teetotaler" in India might develop fatty liver from other metabolic factors (like diet or sugar), while a moderate European drinker might show less immediate liver damage - their genetics act as a more efficient "waste management" system.

Diet

Talking about food habits, Dr Vyas highlights a significant contrast between the Mediterranean-style habits common in Europe and the typical nutritional patterns found in India. He explains that Europeans generally benefit from a diet rich in complex carbohydrates, high-quality proteins, and healthy fats derived from sources like seafood and olive oil.

These nutrients provide the liver with the essential building blocks it needs for repair and protection against inflammation. In contrast, many Indian diets rely heavily on refined carbohydrates and often lack sufficient protein and healthy essential oils.

This high intake of refined sugars and flours can lead to insulin resistance, causing the liver to store excess energy as fat. Consequently, even an Indian teetotaler may develop a fatty liver due to these metabolic stressors, whereas a European's liver might remain more resilient despite moderate alcohol consumption because it is better supported by their overall nutritional intake.

Exercise

Using his Italian patient as an example, the doctor noted a commitment to daily exercise lasting 30 to 40 minutes, supplemented by walking 5 to 6 kilometers every single day. This level of consistent movement is far less common among the Indian population, where regular workouts are often neglected.

Dr Vyas concluded that while even small amounts of alcohol remain toxic to the human body, the superior lifestyle of many Europeans, combined with genetic advantages, a nutrient-dense diet and high physical activity, creates a "buffer" that helps their systems compensate for the damage.

In contrast, the sedentary habits and nutritional gaps seen in many Indian lifestyles leave the liver far more vulnerable to disease, even in those who avoid alcohol entirely.

Experts Warn Of The Dangers Of Suicide Ideation: All You Need To Know

Updated Feb 17, 2026 | 04:01 PM IST

SummarySuicidal ideation involves thoughts of ending one's life, ranging from passive desires to active planning. Driven by biological, environmental, and identity-related stressors, these thoughts signal deep exhaustion. Prevention focuses on recognizing warning signs early, seeking professional help, and utilizing emergency helplines.

Suicidal ideation refers to thinking about or planning one's own death. In simple terms, it involves thoughts of dying or formulating plans to end one's life. While it is not a formal medical diagnosis, it is a serious symptom that can lead to suicide.

Suicidal ideation is generally divided into two categories which include passive ideation, defined as thinking about death or wishing one were dead without a specific plan to act as well as active ideation, defined as formulating specific, elaborate plans to carry out the act.

The active ideation stage is particularly dangerous as it moves from merely thinking of suicide towards self-harm.

What Leads to Suicidal Thoughts?

There is no single cause for these thoughts; rather, they are often the result of complex, overlapping factors. One therapist on Reddit shared a poignant perspective, describing the urge as an "act of mercy" from a tired mind.

She explained: "Suicidal parts are also deeply perceptive. They see suffering that others overlook. They recognize when other coping strategies are failing and, in their exhaustion, believe that the only mercy left is to stop everything altogether".

Common contributing factors include:

  • Biological Factors: Genetics and brain development.
  • Demographics: Age, education, employment, and socioeconomic status.
  • Environmental Stress: Negative life events, interpersonal relationship issues, and chronic stress.
  • Identity: Challenges related to sexual orientation or being transgender/non-binary.
  • Health Issues: Substance use disorders or underlying mental health conditions like depression, anxiety, or psychosis.

The Warning Signs You Need To Keep An Eye Out For

Early intervention is key. Some of the most common warning signs include:

  • Feeling empty, trapped, or hopeless
  • Feeling extremely sad, anxious, or angry
  • Talking about wanting to die or being a burden to others
  • Preparing for suicide, such as making a plan or researching methods of suicide
  • taking dangerous risks, such as driving fast
  • displaying large shifts in mood
  • wanting to give away your possessions or treating people as if you might not see them again
  • withdrawing from friends
  • eating or sleeping significantly more or less
  • using drugs or alcohol more often

Prevention and Support

Studies says we cannot stop our brain to forming such thoughts, noticing the signs early can prevent drastic outcomes. Support is available at both professional and personal levels. Here is what you can do if you are concerned about yourself or someone you know:

  • Seek Professional Help: Enroll in counseling or consult medical institutions specializing in mental health.
  • Find Community: Isolation often worsens ideation. Joining support groups can help individuals feel less alone.
  • Self monitoring: Keeping track of situations you find stressful and how you handle them. Also regularly journaling helps you understand and manage your feelings.
  • Stress Management: Incorporate physical activity and maintain open communication with trusted friends.
  • Emergency Action: If you or someone you know is in immediate danger, call emergency services such as 022 2754 6669 or local helplines immediately.

According to the National Crime Records Bureau (NCRB), India recorded 171,418 suicides in 2023. The data reveals that daily wage earners remain the most affected group, followed by students and young adults. Geographically, Maharashtra, Tamil Nadu, Madhya Pradesh, and Karnataka account for the highest share of these cases.
