AIIMS doctor says cancer relapse can be prevented if you start with these 4 lifestyle habits
In an interview with HT Lifestyle, Dr Poonam Sharma, Associate Professor and Officiating Head - Department of Pathology at AIIMS Jammu, shared that relapse rates vary by cancer type: Breast cancer shows 10% locoregional relapse rates despite optimal treatment
Non-metastatic Ewing sarcoma has 2-10 year relapse windows in many patients
Early relapsed breast cancer (within 8 months) correlates with poor prognosis.
Dr Poonam Sharma answered, 'Our genes can significantly affect the chances of a cancer returning. Some people inherit genetic mutations that make their cancer more likely to come back. For instance, certain mutations—such as those in the TP53 or PIK3CA genes—are commonly found in relapsed breast cancers. In other cases, new genetic changes can develop in cancer cells over time, making them more aggressive or resistant to treatment.' Findings suggest that night shifts disrupt natural 24-hour rhythms in the activity of certain cancer-related genes, making night shift workers more vulnerable to DNA damage while also causing the body's DNA repair mechanisms to be mistimed to deal with that damage.(Unsplash)
She revealed, 'Researchers have also found that some inherited genetic variants can explain why certain groups of people are at higher risk for relapse. For example, specific genetic markers help explain why relapse rates differ between racial groups in childhood leukemia.' Genetics and cancer relapse
Genetics matter more in some cancers than others. Dr Poonam Sharma explained, 'In breast cancer, for example, researchers have found that certain gene mutations are common in cases where the cancer comes back. Ewing sarcoma, a rare bone cancer, can also be more likely to return if certain genes are active. Bladder cancer and some childhood leukemias (like acute lymphoblastic leukemia) are also influenced by specific genetic factors.' The connection between diet and gene regulation highlights the potential for dietary interventions in preventing colorectal cancer.(AdobeStock)
She added, 'In these cancers, knowing about your genetic makeup can help doctors personalize your care. For example, if you have a gene that increases your risk of relapse, your doctor might recommend more frequent check-ups or different treatments to help keep the cancer from returning.' Lifestyle and cancer relapse
According to Dr Poonam Sharma, modifiable factors significantly affect outcomes: Diet: Western dietary patterns increase recurrence risk vs Mediterranean diets. Weight management: Obesity correlates with 30-40% higher mortality in survivors. Physical activity: Reduces all-cause mortality by 43% in cancer survivors. Substance avoidance: Smoking cessation lowers recurrence risk by 22%.
Dr Poonam Sharma pointed out, 'While genetics determine baseline risk, lifestyle modifications can mitigate approximately 30% of relapse risk through metabolic regulation and immune modulation. Breast and colorectal cancers show particularly strong lifestyle interaction effects.'

Prenatal yoga: Doctor shares dos, don'ts and trimester-friendly asanas for a safer practice
Pregnancy brings several mental, physical, and emotional changes, from swollen ankles and nausea to discomfort and mood swings.

Follow these tips to practice yoga during pregnancy.(Freepik) Furthermore, Dr Sonu also explained how yoga helps in supporting health during pregnancy. He said, 'As the body adapts to support new life, yoga can be a powerful companion through this journey by offering emotional balance, improved circulation, and better sleep. For women who have conceived through IVF or have a high-risk pregnancy, yoga offers physical benefits and a sense of calm and connection. The key is personalisation, moderation, and listening to your body. Just make sure to stay hydrated and rest well. Always carry a water bottle to class, and take frequent breaks.

Don'ts: Pregnancy yoga needs to follow certain precautions to ensure safety. So knowing what to skip is just as important as knowing what to practise. Skip inversions and deep twists: Poses like headstands, shoulder stands, or full wheels are a strict no. They can disturb blood flow to the uterus and increase the risk of injury.

Why should children sit down on the floor and eat food: 5 stellar benefits
Recently, a Bengaluru based nutritionist's ( post grabbed attention, in which she spoke about Baby led weaning (BLW-offering your child finger food that they can eat on their own). For this, she put up a video in which her child is eating on her own on a high chair, but so is her househelp's child, but on the floor. While her idea was to talk about how BLW is part of our Indian tradition, she was brutally trolled for making her househelp's kid sit on the floor. However, the trolling apart, many users commented that sitting on the floor is actually beneficial for a child, though it might sound a little unconventional to the Western world. Here is how eating on the floor can support your child's development. Enhances Sensory Development Eating on the floor allows children to see and feel food "upfront". This "food play" is incredibly beneficial for sensory development. Children can explore different textures, colors, shapes, and smells of food items, which acts as a sensory playground . Squishing, squeezing, and manipulating food helps strengthen hand-eye coordination and fine motor skills. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo For picky eaters, this can actually be quite helpful. By interacting with food, children can gradually become more comfortable with unfamiliar foods, which they were earlier too anxious to try. This exploration activity encourages independence and self-feeding skills, as children naturally use their hands to eat.

This ergonomic position can reduce fatigue, improve attention during mealtime, and even decrease the risk of choking.

Makes them independent When children eat on the floor, they often have more freedom to explore food at their own pace, without someone nagging them.

Allowing children to have this control over their eating process helps them build confidence in their abilities. This is crucial for overall development, teaching them not only about nutrition but also about mealtime behavior and responsibility . Improves Communication Mealtime is an excellent opportunity for interaction, and eating on the floor as a family can really strengthen family bonds. This experience makes conversations easy, fostering improved language and communication skills. Children can learn new vocabulary related to food, colors, textures, and tastes. Additionally this technique promotes cooperation and sharing with siblings, and friends. Making mealtimes a fun and relaxed activity by allowing exploration also develops a child's interest in eating, encouraging happy and healthy habits . Boosts Creativity Embracing messy mealtimes (yes, messy is good!) and floor eating can truly foster creativity and imagination. When children are given the freedom to play with their food, their creativity really improves, and this imaginative play stimulates their artistic side and encourages problem-solving skills. Just make sure the floor is clean and sanitized, when your child sits down for a meal, since there will be inadvertent spills that can be cleaned up later.
