Imagine this. A young teenager, 17, years old, who is fully developed. Now imagine this, the same teenager has a fully developed extra set of limbs and a pelvis. That extra set of pair is attached with chest artery. But, how can this happen?

While it is extremely rare, and has a chance of less than one case occurring per 100,000 births. Such things do happen. This is called parasitic twin.

What Is A Parasitic Twin?

It is an extremely rare type of cojoined twin where a baby is born with an underdeveloped twin attached to its body. This condition is also known as vestigial twins. The condition is very closely related to conjoined twins, where babies are connected at birth and share organs. However, the main difference is that in conjoined twins, there are two developed babies, whereas in parasitic twins, only one is fully developed, other one is underdeveloped and non functional.

In such a case, the twin who is developed is medically known as the autositic or the dominant twin. The dominant twin is healthy in most aspect but may have extra tissue, organs, or limbs from the parasitic twin.

The parasitic twin may be attached with the dominant twin through several places. The common joints are at the head, torso, chest, pelvis, buttocks, or back. In these cases, the parasitic twin is not alive and they die either in the womb or during the childbirth.

Doctors Remove Parasitic Twin

Now, let's go back to the case we referred to, where a young teenager had an extra pair of limbs attached to chest. The teenager who has not been named is from Uttar Pradesh's Unnao neighbourhood, and was treated in AIIMS, Delhi. The team of doctors successfully removed the extra set of limbs from his body.

Dr Asuri Krishna, who led the team of specialist who surgically removed the extra limbs told the BBC that only 40 to 50 cases of parasitic twins have been documented in world medical literature, and in those cases, the surgery had been attempted on children. The doctor said that without much medical literature to guide them, the team of doctors depended on "intuition, skill and knowledge".

The doctor shared that the child had two fully formed legs, buttocks and external genitalia, which weighed around 15kg "protruding from his abdomen".

How Was The Surgery Performed?

The doctor shared that first they identified how interconnected the parasitic and host twins were. The doctors took scans and found that parasitic twin was attached to the teen's breastbone. The blood was being supplied from a vessel in his chest. However, "there wasn't much connection with other main organs like the liver or kidneys," said Dr Krishna. The team also found a large cyst in the teen's abdomen.

Then the surgery was performed in two stages. In the first stage, the parasitic twin was removed. Then the cystic mass was extracted from the surrounded area. The entire surgery was completed in two and a half hours and the team of doctors included radiologists, anaesthetists, and plastic surgeons.

The biggest challenge was when the teen's blood pressure dropped as 30 to 40% of his blood flowed to the parasitic twin, however, the doctors were prepared for it and they stabilized him.

Breast Cancer: New Genomic Test May Help Patients, Opening Personalized Treatment Options

Updated May 31, 2026 | 10:00 PM IST

SummaryThe Optima trial by the University College London shows that a new genomic test may detect the risk range of breast cancer, and if it's low, then it allows avoiding chemotherapy and choosing hormone therapy.

According to the Indian Council of Medical Research - National Cancer Registry Programme (ICMR-NCRP), India reports about 220,000 new cases every year, and the common treatment procedure for this disease is chemotherapy, which comes with profound fatigue, hair loss, nausea, compromised immunity, and nerve damage.

The University College London led the Optima trial, which studied over 4000 patients with the disease in different parts of the world, and a low score on the genomic test could be mediated with only hormone therapy.

The trial’s chief investigator and a professor of breast oncology at UCL, Professor Rob Stein, explains that the study used tumour biology to guide decisions instead of relying on traditional clinical procedures.

The research had 4,429 women participants above the age of 40 years with hormone-positive breast cancer. These patients were then divided into two groups based on the genomic test results by the researchers, and one group with a higher risk was given chemotherapy along with hormone therapy, while the others were only treated with hormone therapy.

What Is Breast Cancer?

Breast cancer refers to the uncontrolled growth of the cells that are found along the inner lining of breast tissue. This out-of-control growth of cells leads to the formation of tumours. The tumour can be “invasive”, meaning that it spreads to the nearby tissues outside the breast, or “in situ”, where the tumour does not spread outside the breast region.

Usually, the “in situ” type of tumour is non-cancerous and non-life-threatening. However, in the case of invasive tumours, the cancerous cell mass can spread to the lymph nodes and further metastasise, that is, spread to other body parts. About 80% times the breast cancer cases are invasive. Hence, upon noticing symptoms like lumps, changes in breast shape, or abnormal nipple discharge, you must promptly consult a doctor.

While both men and women can develop it, in 99% of cases of breast cancer, women are seen to be affected by it. Only 0.5 to 1% of men are affected due to this condition. Furthermore, the condition is mostly prevalent in women aged 50 or older.

Pairing Ozempic With Exercise Is Beneficial For Your Muscles, Study Finds

After the advent of Ozempic-like drugs, the treatment of obesity has completely changed. Millions of people throughout the world use the medication either for obesity or diabetes. Although there were always concerns among medical professionals that the medication not only reduces fat but also lean muscle, which in turn leads to health loss, as muscle is very important to long-term health.

Now, a new study presented at the European Atherosclerosis Society (EAS) Congress 2026 claims that this vital minus point of the drug, causing lean fat loss, can be mended by pairing it with exercise. The study suggests that combining the drug with exercise can lead to better fat loss, while the muscle will also stay protected. Though the study was done on animals, further research on humans is required.

The researchers studied mice with obesity, insulin resistance, fatty liver disease, and atherosclerosis. The animals were divided into groups and given semaglutide. After 14 weeks, it was found that the drug alone reduced fat by 31 percent but also caused muscle loss, while when the medication was given with exercise, it caused fat loss by 45 percent, and lean mass loss was minimal.

How Does Ozempic Function?

The first thing to remember here is that Ozempic is a brand-name medicine that contains semaglutide as its active ingredient. Semglutide is the synthetic version of GLP-1, a natural hormone produced in the intestines that regulates blood sugar, appetite, and digestion. Now, every time you eat, your body produces various hormones, including GLP-1. These are called post-nutrition hormones and help you absorb the energy you just consumed.

GLP-1 travels to your pancreas, prompting it to produce insulin. It also travels to the hypothalamus in your brain, which gives you the feeling of being full or satiated. Ozempic imitates this hormone, thereby silencing the food chatter in the brain. Interestingly, for some people this food chatter is really quiet ( people with low appetite), and for others it is an outburst (people who generally binge eat). So with Ozempic, silencing this self-talk in the brain, people tend to lose their appetite and eventually weight.

However, it is important to note that losing weight includes not just fat but muscle as well. Losing too much muscle can lead to reduced strength and a shorter life span. Notably, records show that most people who start taking them stop them at 12 weeks; therefore, it is important for some but not for others.

Ice cream is a sweet and delicious dessert loved and enjoyed by millions every day, and summers without this soothing treat are unimaginable, but some get a sharp stabbing pain after they have it. This headache is brain freeze, and it can reveal a lot about your health condition.

Amaal Starling, a neurologist at the Mayo Clinic in Minnesota, in the US, says, "Ice cream headache is very, very common." She added, "It's harmless, it comes, and it goes."

What Is Brain Freeze?

Scientists refer to brain freeze or ice cream headache as a cold-stimulus headache. According to the researchers, the reason for this condition is "rapid cooling at the roof of the mouth, or even in the very back of the throat". This cooling causes the blood vessels to shrink quickly after they return to their normal state. Which is the source of pain?

Why Do Some People Get These Ice Cream Headaches?

The research indicates that brain freeze seems to run in families. Though it also gets affected by your non-ice cream headaches, as people with migraines tend to feel far worse pain in brain freeze than others.

What Are The Common Headaches?

Stress Headaches

Stress headaches, also known as tension headaches, usually feel like a tight band squeezing your head. They are commonly caused by long working hours, lack of sleep, dehydration, or anxiety. However, these headaches generally go away with simple fixes, like rest, water, and relaxation techniques like yoga or meditation.

Migraines

Migraines often cause throbbing pain on one side of the head, along with nausea, vomiting, or sensitivity to light and sound. Some people also experience visual disturbances known as ‘auras’, flashes of light or zigzag patterns, before the headache even begins. They can last for hours or even days and may seriously impact the quality of life. Unlike stress headaches, migraines often need specific medication and lifestyle management.

When Do Headaches Mean Something More Serious?

Not every headache is about stress or migraines. Sometimes, a headache is a warning siren for something far more dangerous. Headaches can also indicate conditions such as high blood pressure, brain infections, stroke, or tumours. The red flags to look out for include:

  • Sudden, severe headache (often described as the ‘worst headache of your life’)
  • Headaches with vomiting, vision loss, or confusion
  • Headaches after a head injury
  • Headaches that worsen over time
  • Headaches linked with fever or neck stiffness
