We all must have come across the phase: this is why women live longer than men. These are all over the social media, where men are performing more often than not, some experiments, without gears, just for fun, "in the name of science". The caption reads: this is why women live longer. However, is there really a science to it, other than the fact that women choose to do things more safely?

In the United States, women have a life expectancy of about 80, whereas men have 75. Women outlive men and this holds true regardless of the country women live, the money they make, and other factors. In fact, it is true for most other mammals too.

Dr Dena Dubal, a professor of neurology at the University of California, San Francisco told the New York Times, "It is a very robust phenomenon all over the world, totally conserved in sickness, during famines, during epidemics, even during the times of starvation."

But what are the reasons? These reasons are often more complicated and less established. It is important to note that only because women are outliving men does not mean they are living a better life. In fact, women tend to have shorter health spans, which means the number of healthy years in a person's life is less in women than men, confirmed Bérénice Benayoun, an associate professor at the U.S.C. Leonard Davis School of Gerontology.

As per a 2021 study titled, Sex differences in frailty: Comparisons between humans and preclinical models, found that women are more physically grail than men in old age. They are also more vulnerable, especially after menopause and are at more risk of developing cardiovascular issues and Alzheimer's disease because of age.

The key is in figuring out what makes one sex more resilient or vulnerable.

Genetics

For things which do not find easy explanations, scientists look for their answers in genes. Many research, including a 2020 study titled, The sex with the reduced sex chromosome dies earlier: a comparison across the tree of life, suggests that the XX set of female sex chromosomes may impact longevity. However, there has not been any clarity on how it affects longevity.

Another 2018 study titled, Female XX sex chromosomes increase survival and extend lifespan in aging mice, which was conducted by Dr Dubal's lab, looked at genetically manipulated mice with different combinations of sex chromosomes and reproductive organs. It was found that those with two X chromosomes and ovaries lived longest, followed by mice with two X chromosomes and testes. Mice with XY chromosomes had shorter life spans.

"There was something about the second X chromosome that was protecting the mice from dying earlier in life, even if they had testes. What if there was something on that second X chromosome that was in some ways a sprinkle of the fountain of youth," says Dr Dubal. While scientists have not yet looked at this factor in humans, Dr Dubal suggests that humans have the same hormones and sex chromosomes, and similar reproductive system that could corroborate the similar findings in people.

Hormones

Plenty research has shown that estrogen is responsible for longevity also effect on the immune system. The data also shows that before menopause, the female immune system tends to do better. In fact Dr Benayoun said that males tend to do much worse in response to infection.

Another 2017 study titled, Ages at Menarche and Menopause and Reproductive Lifespan As Predictors of Exceptional Longevity in Women: The Women's Health Initiative, found that women who experienced menopause later in life over the age 50 lived longer than those who experienced it earlier.

Lifestyle and Behavior

There are also disparity in behavioral patterns between men and women. This includes smoking, drinking heavily, which can contribute significantly to mortality. Women also have more "health promoting behavior", believe experts. Women are also more likely to socialize than men and thus it protects them from detrimental effects of social isolation and loneliness. In fact, a 2023 analysis published in Jama Network, titled, Widening Gender Gap in Life Expectancy in the US, 2010-2021, found that women are less likely to die by drug overdose or suicide.

Jane Fallon, Ricky Gervais’ longtime partner, recently opened up about being diagnosed with breast cancer. The producer of 20 Things To Do Before You’re 30, Fallon explained that her breast cancer was diagnosed during a routine mammogram in December.

“About a month ago I was diagnosed with breast cancer - very early stage thankfully & the prognosis is excellent. I had a routine mammogram a week before Christmas.” She explained that she had no symptoms however; it was her regular check-ups that helped the early diagnosis.

“I had no symptoms, but the brilliant radiographer spotted something iffy & sent me for further tests & eventually a biopsy” With biopsies and an MRI, her healthcare team located the “problem area” and now her surgery has been scheduled for next week.

Why Early Diagnosis Matter For Breast Cancer

According to the Center of Disease Control and Prevention (CDC), breast cancer screening is a proactive checkup used to find cancer before any physical signs or symptoms appear. While screening doesn’t prevent cancer, its goal is early detection, making the disease much easier to treat.

Since every person’s body and history are different, you and your doctor should engage in informed and shared decision-making. This means discussing the pros and cons to decide together if, and when, screening is right for you.

The U.S. Preventive Services Task Force (a group of national medical experts) provides guidelines based on the latest research:

Average Risk

Women aged 40 to 74 should generally get a mammogram every two years.

High Risk

If you have a family history or other risk factors, your doctor may recommend a different schedule or additional tests.

How Is Breast Cancer Screening Done?

There are two main imaging tools used to look for breast cancer:

Mammogram

This is a specialized X-ray and remains the "gold standard" for most women. It can spot tumors long before they can be felt, significantly lowering the risk of dying from the disease.

Breast MRI

This uses magnets and radio waves for a detailed image. It is typically reserved for women at high risk and is used alongside a mammogram, rather than instead of one.

Breast Cancer Awareness Starts At Home

Staying informed about your body through physical checks is a key part of proactive health. A clinical breast exam involves a healthcare professional using their hands to feel for any unusual lumps or changes in texture.

Parallel to this is breast self-awareness, which encourages you to become familiar with the normal look and feel of your breasts. While neither practice is currently proven to lower the overall risk of death from cancer, they remain vital for identifying immediate concerns like pain or size changes.

Navigating healthcare requires a careful balance of pros and cons, which is why informed and shared decision-making is so important. Every screening test involves a trade-off; while the goal is protection, there is always a possibility of encountering false positives or overdiagnosis.

What Are The Benefits of Early Screening?

The primary advantage of regular breast cancer screening is the ability to achieve early intervention.

When cancer is detected in its earliest stages, often long before a physical lump can be felt, it is typically much smaller and confined to a localized area.

This makes the disease significantly easier to treat and often allows for more successful outcomes with less aggressive medical procedures.

Ultimately, consistent screening provides the best opportunity to find and address issues before they become life-threatening or difficult to manage.

The Supreme Court of India, in a landmark judgment allowed 32-year-old Harish Rana, who had been living in a vegetative state for last 13 years, the right to die. This means, that the apex court allowed passive euthanasia for Rana. The bench comprising Justice JB Pardiwala an Justice KV Vishwanathan allowed the withdrawal of life support of Rana, who has been in a coma and kept alive on tubes for breathing and nutrition after he sustained severe head injuries following a fall from a building in 2013 in Chandigarh.

The judgment is a win, however, Ashok, Rana's father said that his feelings are mixed. "As a father, this is extremely painful. But on humanitarian grounds, this is the best we can do for my son." He continued, "It is just not a matter of my son, but there are many others in such a state in the country. I think it is the grace of God who guided the Supreme Court judges... I am happy that with this judgments, many others may find a way."

While, this is a landmark judgment, India's conversation on right to die has evolved slowly. What shaped the judgment is also the years old case of Aruna Shanbaugh. This was the case that set the legal framework for right to die, so it could be implemented in practice years later in Rana's case.

The Cases That Shaped India's Right To Die

If one could trace the earliest debates that began around the "right to die", one could not overlook Gian Kaur v. State of Punjab (1996). This is where a three-judge bench of the Supreme Court upheld the constitutional validity of the offence of abetment of suicide under the Indian Penal Code. The apex court ruled that right to life under Article 21 does NOT include a right to die.

While the court did not rule on the validity of active or passive Euthanasia, it did make an important observation, which was later used in the coming euthanasia jurisprudence.

The court noted that the right to live with human dignity would also mean the existence of such a right upto the end of natural life. This means the right to a dignified life upto the point of death, which also includes a dignified procedure of death.

Fast forwarding to 2006, the 196th Law Commission of India said that withholding life support or medical treatment of terminally ill patients does not attract criminal liability of attempt to suicide. The court noted that such a action should be done provided it is done in the best interest of the patient.

Aruna Shandbaug Case

In India, euthanasia is allowed under strict guidelines and is only legalized with the withdrawal of life support for terminally ill patients, which means, passive euthanasia. The landmark case if of Aruna Shanbaug, a nurse at King Edward Memorial Hospital who had been kept in a vegetative condition for more then four decades for finally to be granted passive euthanasia, that too "only by legislation", which means the process must be followed until Parliament makes legislation on this subject.

Shanbaug was a victim of a brutal sexual assault in 1973 that deprived oxygen supply to her brain. In 2009, journalist Pinki Virani approach the Supreme Court to seek permission for euthanasia on Shanbaug's behalf. This was met with much criticism, including from the community of nurses who were taking care of Shanbaug since decades. However, many reports show that despite the care, Shanbaug's condition in hospital continued to worsen.

The court in 2011 refused euthanasia largely due to the opposition from hospital staff who cared for her. However, it did deliver a historic ruling and legalized passive euthanasia in India, subject to prescribed safeguards and High Court approval, and made it lawful "only by legislation", as explained above.

The Important Of Living Will And Right To Die With Dignity

Dr Rajeev Jayadevan, a physician with extensive international clinical experience and a strong interest in public health wrote for Health and Me on the importance of living will. He also noted that recent legal developments "have highlighted the importance of advance planning for end-of-life care".

The doctrine evolved further in Common Cause v. Union of India (2018), when a Constitution Bench of the Supreme Court led by then Chief Justice Dipak Misra recognized that the right to die with dignity is part of Article 21 of the Constitution.

The court ruled that passive euthanasia is legally valid. It said that while the sanctity of life must be respected, in cases of terminal illness or patients in a persistent vegetative state with no hope of recovery, priority should be given to the patient’s advance directive and right to self-determination.

The judgment also introduced the concept of advance medical directives, or “living wills”.

A living will is a written document in which a person can specify in advance the medical treatment they wish to receive if they become terminally ill or are no longer able to give informed consent.

It can also allow family members to withdraw life support if a medical board determines that the patient cannot recover.

The ruling strengthened patient autonomy by allowing people to make decisions about their end-of-life care even when they cannot communicate those wishes later.

What Has Changed Through Judgments?

While the 2018 ruling recognized living wills and passive euthanasia, the process was very complicated. It required approvals and countersigning by a judicial magistrate and multiple procedural steps, which made it difficult for families and hospitals to follow.

In 2019, the Indian Council of Critical Care Medicine told the Supreme Court that these rules were too hard to implement.

In 2023, a Constitution Bench simplified the process. Living wills no longer need a magistrate’s signature and can be attested by a notary or gazetted officer. More than one family member can be named as a decision-maker. Hospitals now rely on two medical boards that must give an opinion within 48 hours, and they only need to inform a magistrate rather than seek approval.

The issue came to the forefront in the case of Harish Rana, who suffered severe brain injuries after a fall in 2012 and showed no recovery for 13 years. In 2024, his family approached the Supreme Court seeking permission to withdraw life support.

The court allowed it, saying continuing treatment was not in his best interest.

Legal experts say this marks a major shift in India’s approach to passive euthanasia. Over the years, court rulings have strengthened the idea that the right to die with dignity is part of Article 21, simplified procedures for living wills, and shown greater willingness to balance the sanctity of life with dignity at the end of life.

A new analysis by the American Cancer Society observed that colon cancer or colorectal cancer has now become the leading cause of cancer death in US for people under 50. As per the report from the American Cancer Society, adults who are 65 or younger comprise nearly 45 per cent of all new colorectal cancer cases. This is a significant increase from 27 per cent in 1995.

Dr Timothy Cannon, director of the Molecular Tumor Board and co-director of the Gastrointestinal Cancer Program at Inova in Virginia who spoke to Fox News Digital said, "Once considered a disease that primarily affected people over 50, we are now seeing increasing diagnoses in patients in their 20s, 30s and 40s — making it even more important not to dismiss symptoms based on age alone."

How Can You Detect Colorectal Cancer?

Doctors and experts across say that early screenings could help. Health officials recommended screenings to start at the age 45 and continue through age 75 for adults at "average risk".

Other ways could also be stool-based test that are used to detect blood or DNA changes, which could be potential indicators of colorectal cancer.

A colonoscopy is another method, a medical procedure that allows a doctor to examine the inside of a patient's colon and rectum. It uses a thin, flexible tube with a camera on the end. It is typically done every 10 years for adults at average risk.

"Colonoscopy remains the gold standard because it not only detects cancer early but can also prevent it by identifying and removing precancerous polyps," said Cannon.

Dr Michael Martin, who is a California-based physician, however, emphasized that colonoscopy is usually done for younger patients who are at higher risk.

As per Dr Martin, Stool-based tests are appropriate screening options for average-risk adults, but they are not the best choice for people with significant family history, inflammatory bowel disease, hereditary syndromes or alarm symptoms. If symptoms are present, the goal is not screening but diagnosis, and colonoscopy is usually the more appropriate test."

Who Should Get Screened For Colorectal Cancer Before 45?

There are three kinds of people who could get their colon cancer screened before turning 45. Experts suggest these people are as followed:

People With Strong Family History

The American College of Gastroenterology recommends early screening if one first-degree relative is diagnosed with colorectal cancer, or an advanced polyp before age 60, or if two first-degree relatives are diagnosed at any age.

Symptoms That Are Critical

There are red flags which could hint you to get the screening done before 45, they include:

• Rectal bleeding with bright red blood
• Dark or black stools
• Blood in stool
• Persistent changes in bowel habits like constipation or diarrhea
• Unexplained iron deficiency or anemia
• Ongoing abdominal pain or cramping
• Unexplained weight loss
• Persistent sensation that bowel is not emptying fully

Genetic Condition

Some people with certain genetic condition could have an increased risk of colon cancer, this includes people with Lynch syndrome. This is an inherited DNA mutation that increases lifetime risk. People with this condition should get a colonoscopy every one to two years starting from the age 20 to 25 years, or two to five years before the youngest diagnosed family case, note the National Cancer Institute.
