Oncologist shares 6 causes of sarcoma cancer: Age, gender, genetics and more
1. Genetic mutations
One of the primary causes of sarcomas are genetic mutations, whether inherited or acquired. Certain hereditary conditions significantly increase the risk of developing sarcomas. These include Li-Fraumeni syndrome, neurofibromatosis type 1 (NF1), and familial retinoblastoma. These syndromes are characterised by mutations in tumor suppression genes whose normal cellular function is to regulate growth and which disable the protective function of preventing tumors. When these tumor suppression genes are mutated, the cells are freed to grow uncontrollably, resulting in sarcoma.
2. Radiation exposure
Radiation exposure is another well-documented cause. People who have undergone radiation therapy for other cancers may develop sarcomas in the treated area, sometimes years after the original treatment. These are known as radiation-induced sarcomas. The risk is relatively low but significant enough to be a known concern for cancer survivors.
3. Environmental exposure
Environmental factors contribute, but not to the same extent. Certain chemicals—like vinyl chloride (used to make plastics), arsenic, and herbicides—have some relationship with certain sarcoma subtypes when exposure is done over time. Certain long-term environmental exposures have a less specified association to sarcoma; in addition, such links are mostly occupational. Also read | Is sarcoma cancer always fatal?

4. Lymphedema
Long standing Lymphedema (swelling which is caused by accumulation of lymphatic fluid in body) after breast cancer surgery, is a well-established risk factor for a type of sarcoma called angiosarcoma. Chronic inflammation in the lymphedematous area is believed to promote tumor formation, though the exact mechanisms remain unclear.
5. Injury or trauma
Trauma or injury has often been speculated as a cause, but there is no strong scientific evidence to support a direct link between physical injury and sarcoma development. In many cases, a sarcoma may have already been present and only discovered following an injury to the area.
6. Age and gender
Age and gender may also be related to risk factors. Although sarcomas can occur at any age, certain types are more common in children and young adults, including, but not limited to, Ewing sarcoma and rhabdomyosarcoma. Other types, such as liposarcoma, tend to be more common in older adult populations. Some studies also show a slight increase in incidence in males compared to females.

World Hepatitis Day 2025: Expert shares 5 reasons why hepatitis cases spike in monsoon
World Hepatitis Day 2025: Liver inflammation caused by infections can lead to hepatitis, a condition marked by symptoms such as dark urine, jaundice, and abdominal pain. Cases of hepatitis often see a noticeable rise during the rainy season. Also read | Hepatitis alert: Gastroenterologist lists 8 groups of people who are at higher risk; shares when to get tested Hepatitis cases spike in the rainy season.(Shutterstock) Commenting on this, in an interview with HT Lifestyle, Dr Aravind Badiger, Technical Director, BDR Pharmaceuticals said, 'Hepatitis A and E, especially, are spread mainly due to the intake of infected food and water. With heavy rains, poor hygiene, waterlogging, and damage to clean water supply lines provide perfect opportunities for such outbreaks.' Dr Aravind Badiger further shared the reasons why hepatitis cases spike during the rainy season: 1. Contaminated drinking water is the leading cause Mixing of sewage and drinking water is generally caused by flooding and leaking pipelines during the monsoon season. This contamination is a significant source of hepatitis virus outbreaks, particularly in the urban and semi-urban areas, which are densely populated. Consumption of a small amount of contaminated water or raw food washed in it may cause infection. 2. Unhygienic food practices amplify risk The open-air food, such as street food, cut fruits, and juices, is usually subjected to rainwater and unhealthy environments. The food handlers might fail to observe hygiene, and this raises the chances of viral transmission. These seasonal activities are some of the reasons that lead to increased cases.

Symptoms often overlooked or misdiagnosed Hepatitis has common symptoms of fatigue, fever, loss of appetite, nausea, yellowing of the skin (jaundice), and dark urine, which are usually similar to other monsoon diseases. This leads to late detection of the disease, thus giving the virus time to spread and complications to intensify. 4. Prevention is often ignored Drink only boiled or RO-filtered water. Raw fruits or salads and street food should be avoided during the monsoon. Make sure to wash your hands with soap before meals. Keep food in clean, covered containers. Hepatitis A and B vaccination should be considered, particularly in high-risk patients. 5. Community awareness and early action are crucial Chlorination of water supply, frequent inspection of restaurants, and sensitization during monsoon should be the target of the public health systems. One can avoid long-term liver damage by being vigilant of the symptoms and reporting to the doctor at the first instance.

Hepatitis alert: Gastroenterologist lists 8 groups of people who are at higher risk; shares when to get tested
Liver inflammation caused by viral infections can result in hepatitis, a condition that may present with symptoms such as dark urine, jaundice, fatigue, and abdominal pain. Depending on the type of infection, hepatitis can be either acute or chronic. Certain groups of people, however, are at a significantly higher risk of contracting the disease. Also read | Hepatitis can cause liver disease: Gastroenterologist shares common causes, symptoms, prevention tips Know who are at an increased risk of getting hepatitis. (Freepik) In an interview with HT Lifestyle, Dr. Gourdas Choudhuri, chairman, gastroenterology and hepatobiliary sciences, Fortis Memorial Research Institute, Gurugram shared who are at an increased risk of getting hepatitis. 1. Healthcare professionals Healthcare professionals, including doctors, nurses, and lab technicians, face occupational exposure to infected blood and body fluids. 2. Patients exposed to dialysis Patients on long-term dialysis may be at risk, especially if infection control practices are inadequate. 3. Patients who received blood transfusion Anyone who received a blood transfusion or organ transplant before 1992 should consider getting tested, as blood screening for hepatitis B and C became more stringent after that time. 4. Newborns Newborns of hepatitis B-infected mothers can contract the virus during delivery if appropriate precautions aren't taken. 5. People with HIV People living with HIV often share common routes of transmission and may be co-infected with hepatitis B or C. 6. People in close contact with hepatitis patients Close household contacts of hepatitis B or C patients may also be at risk through shared items like razors or toothbrushes that can carry microscopic amounts of blood. 7. People with multiple sexual partners Individuals with multiple sexual partners or those engaging in unprotected sex are at risk, particularly for hepatitis B, which can spread through bodily fluids.

People who inject drugs People who inject drugs or share needles are at significantly higher risk for both hepatitis B and C due to possible blood contamination. When should you get tested for hepatitis?(Shutterstock) When is it essential to get tested for hepatitis? If you're experiencing symptoms such as prolonged fatigue, unexplained weakness, jaundice (yellowing of eyes or skin), dark-colored urine, abdominal discomfort, nausea, or loss of appetite; these can all be signs of hepatitis. If your liver enzymes are elevated on a routine blood test, even in the absence of symptoms, it's important to investigate further. Anyone with a history of high-risk exposure, including needle use, tattoos or piercings in unregulated settings, or unsafe medical procedures, should be screened. Also read | Truth about viral hepatitis: Facts, myths and stigma If you've been in close contact with someone who has hepatitis, testing is strongly advised, even if you feel well. Women who are pregnant or planning pregnancy should be screened early to prevent mother-to-child transmission.

Is your acne itching? Dermatologist reveals it may be fungal acne, shares how to tell the difference
The monsoon season triggers a lot of skin conditions because of the weather conditions. One of them is fungal acne, which many people mistake for regular acne because of overlapping symptoms like breakouts and redness. In an interview with HT Lifestyle, Dr Amit Bangia, Associate Director- Dermatology at Asian Hospital, shared with HT Lifestyle how to spot the differences between regular and fungal acne. Acne may look alike, but may have different root causes. (Shutterstock) ALSO READ: Struggling with jaw and chin acne? Dermatologist says it could be hormonal, shares 5 ways to treat them Dr Bangia highlighted the concern of growing skin infection cases in monsoon and said, 'During the monsoon, high humidity and dampness create the perfect conditions for rapid growth of microbes like bacteria and fungi. This often results in a rise in skin infections, reflected in the noticeable increase in dermatology outpatient visits across the country during this season.' Distinguishing between regular acne, which may result from skincare missteps or hormonal imbalances, and fungal infection-related flare-ups is important, as it helps guide targeted treatment. What is the difference between fungal and regular acne? Fungal acne has a burning sensation.(Shutterstock) The big difference Dr Bangia revealed when it comes to the cause is that fungal acne is caused by yeast, which is unlike typical acne caused by bacteria. Recognising the causal difference is important as it influences the treatment approach. He said, 'Fungal acne, unlike typical acne, is brought about by an excessive amount of the yeast-like fungi Malassezia. Regular acne results from clogged pores and bacterial proliferation.' Sharing a brief lowdown on the areas where acne typically occurs, he added, 'For the unversed, acne usually arises in areas with a high concentration of oil glands, such as the T-zone (the forehead, nose, and chin). Fungal acne can appear on a variety of body areas, including those with decreased oil production.' Knowing the distinguishing features helps in identifying these two types of acne more accurately. Dr Bangia noted, 'Fungal acne commonly appears as little, itchy lumps on the face that resemble tiny pimples or whiteheads. They can also appear in other body sections like the chest, back, and shoulders. These bumps may be associated with redness and inflammation." "Another noticeable feature is the prevalence of itchy or burning feelings. Fungal acne is often associated with significant itching, but ordinary acne may be less unpleasant,' Dr Bangia shed light on one of the prominent symptoms. Fungal acne is more common in people with compromised immunity, he said, 'such as those with diabetes or HIV, or even patients who use antibiotics regularly, which can lead to an imbalance of bacteria and yeast on the skin.' Treatments Treatments and management strategies differ for both conditions. Dr Bangia noted that if over-the-counter acne treatments and solutions prove ineffective, it may be a case of fungal acne. He said, 'Typical acne can be treated with benzoyl peroxide or salicylic acid, whereas fungal acne requires antifungal medication.' But since prevention is always better and monsoon increases the risk of skin infections, knowing the precautionary methods will keep you a step ahead. Dr Bangia shared, 'First and foremost, people should prioritise personal hygiene, keeping skin dry by choosing breathable cotton and linen fabrics, and using antifungal powders or lotions in vulnerable regions. Bathe with mild antiseptic soaps is are extremely fundamental prophylactic measure.' What are the skincare ingredients consumers use for acne-prone skin? Now, when it comes to regular acne, which is very common, let's take a closer look at the skincare ingredients that skincare enthusiasts are leaning towards. When it comes to managing regular acne, especially among people with sensitive skin, they often incorporate ingredients that help reduce breakouts without irritating the skin. Malini Adapureddy, Founder and CEO of Deconstruct, shared insights on market trends and the key ingredients consumers are embracing for acne-prone skin. She said, 'For sensitive, acne-prone skin, the key isn't just using fewer products—it's about choosing the right ones. This means selecting ingredients that address skin concerns without causing irritation. For instance, consumers choose ingredients like Niacinamide, which can soothe inflammation and regulate oil production, while Alpha Arbutin helps fade dark spots gently over time. When used in the right concentration, even active ingredients like Salicylic Acid can cleanse effectively without stripping the skin."
