Stomach cancer is a type of cancer that develops in the lining of the stomach. Also, known as Gastric cancer, it affects the elderly more than the adult. According to the American Cancer Society, about 6 of every 10 people diagnosed with stomach cancer each year are 65 or older. Also, the lifetime risk of developing stomach cancer is higher in men (about 1 in 101) than in women (about 1 in 155).

A health expert, speaking to a leading media house, emphasized five common symptoms of stomach cancer that should not be ignored:

1. Unexplained weight loss: Losing weight without trying or experiencing an unexplained drop in appetite, which may signal cancer progression.

2. Pain in the upper part of the abdomen: Persistent or occasional pain in the stomach area, often after eating, can become more severe as the condition progresses.

3. Frequent vomiting after meals: Nausea, sometimes accompanied by vomiting, may occur especially after meals and is linked to cancer blocking or irritating the stomach.

4. Vomiting blood, which may appear coffee-colored: This can indicate bleeding in the stomach, often caused by ulcers or tumors, and requires immediate medical attention.

5. Black, tarry stools: This occurs when blood from the stomach is digested and passed through the intestines, signaling potential internal bleeding

There are also other concerning signs that should not be overlooked such as jaundice, unexplained weight loss, early onset of diabetes, dark stools, and loss of appetite. Health experts strongly advise seeking immediate medical attention if you notice any of these symptoms. If you or a loved one experience these signs, it's crucial to visit a physician for a thorough evaluation to rule out serious underlying health conditions.

How Does Stomach Cancer Spread?

Oncologist Dr Pankaj Kumar Pande, Director–Surgical Oncology, Max Super Specialty Hospital, Shalimar Bagh, Delhi explained that this form of cancer spreads through three main pathways: Direct spread, lymphatic spread, and bloodstream.

1. Direct Spread: In its early stages, stomach cancer can invade nearby tissues and grow into the deeper layers of the stomach or spread to surrounding organs such as the oesophagus, liver, pancreas, or intestines.

2. Lymphatic Spread: Cancer cells can travel through the lymphatic system. The most common areas affected are the regional lymph nodes near the stomach, particularly those around the liver and diaphragm.

3. Bloodstream: "Cancer cells can enter the bloodstream and travel to distant parts of the body," which is a common route for stomach cancer to metastasize to distant organs.

He further explained that cancerous cells spread from the original tumour to other parts of the body through a process called Metastasis. The most common sites for the spread are the liver, lymph nodes, peritoneum, lungs, bones, and ovaries.

Amid the continuously worsening air pollution and air quality levels in Delhi, the government has implemented a work-from-home measures under the Graded Response Action Plan (GRAP).

As per the notice by the Government of National Capital Territory of Delhi and Department of Environment & Forest, all government offices under the GNCTD and private offices operating within Delhi must now function at 50 percent staff strength, with remaining employees required to work from home.

Administrative Secretaries and Heads of Departments may only call essential staff when necessary. However, the overall attendance cannot exceed the 50 percent limit. Private offices have also been instructed to minimize vehicular movement, adopt staggered working hours, and ensure strict adherence to work-from-home protocols to reduce emissions tied to daily commuting.

Which Offices Are Not Working From Home?

Essential services, however, are exempt from these restrictions. Hospitals, health facilities, fire services, public transport, water and sanitation departments, disaster management agencies, electricity services, and teams involved in pollution control and emergency duties will continue operating normally.

District Magistrates, Deputy Commissioners of Police and local bodies have been directed to ensure strict compliance across all private offices in Delhi. The restrictions take effect immediately and will remain in force for the full duration of GRAP Stage III, or longer if recommended by the Commission for Air Quality Management (CAQM).

Delhi AQI Today

On Tuesday morning, as of 7:30 am, Delhi woke up to 'Hazardous' air with the AQI as per the aqi.in, recorded at 426. The AQI in Delhi is showing 1.7 times higher than India's average AQI.

The particulate matters have long exceeded the safe limits stated by the World Health Organization (WHO). As of today, the PM10 level is 388 µg/m³, which is 8.6 times above the recommended WHO guidelines. Whereas PM2.5 is at 288 µg/m³, which is 19.2 times the WHO guidelines.

What Does The Doctor Say?

Dr Nikhil Modi, a senior consultant, Respiratory Critical Care and Sleep Medicine at Indraprastha Apollo Hospitals in one of his previous video had said that the pollution is an "ever-growing menace". However, he suggests, one can take simple steps to protected against that.

Like all doctors he too suggested to not go out when the pollution levels are at its peak. "You may go out only if it is very necessary, but wear a mask." As per a 2023 study by an air filter brand, Delhi's air pollution peaked at 9AM and gradually improved as the day progressed. On an average, Delhi sees roughly as half as much PM2.5 by 5PM. The doctor also draws attention on the importance of maintaining a good and healthy diet, especially lots of fruits and vegetables, which are rich in antioxidants.

Health Impact Of Air Pollution Beyond The Lungs

A report by the University of Chicago revealed that air pollution is reducing the life expectancy of Delhi residents by 7.8 years. As per a US-based NGO report by the Health Effects Institute, there has been 30 to 50% increase in lung cancer rates associated with pollutants. A recent 2024 study also revealed that air pollution is not just linked to lung cancer but it can also cause head and neck cancer.

Tata Memorial Hospital published a study in July 2024 that revealed most people who had lung cancer in India never smoked.

"Head and neck cancer is a harder link to show, and it has a much lower occurrence than lung cancers, but since they also occur as a result of smoking, similar to lung cancers, we wanted to explore any connections," said John Cramer, the neck cancer study's lead researcher. "Presumably, the link to head and neck cancer comes from what we breathe to that material affecting the lining in the head and neck. We see a lot of occurrences of where carcinogens touch or pool in the body to where cancers can occur," he explained.

The flu season has started earlier than expected in some parts of the country. The cases may erupt as soon as people start to travel, meet more people during the Thanksgiving and other upcoming holidays. However, there have been warning signs of a virus that has already set off massive outbreaks in UK and Canada, called the H3N2 subclade K.

What Is The Flu Strain Subclade K?

It is a variant of the H3N2 virus that had been circulating in other countries over the summers. Experts say the new variant is driving a surge in flu cases across Canada, Japan, and the U.K. Data from the Centers for Disease Control and Prevention shows that of nearly 150 test samples identified as part of the H3 lineage, more than half belonged to the subclade K group.

The influx of patients have been high too, as Dr Cameron Wolfe, a disease specialist at Duke University School of Medicine in Durham, North Carolina suggest, and is reported by the NBC. "At the moment, we’ve had two, three, four per day coming in," he said.

Alicia Budd, who leads the Centers for Disease Control and Prevention’s domestic influenza surveillance team, said flu activity in the United States is expected to rise steadily in the coming weeks.

How Dangerous Is The New H3N2 Flu Strain?

So far, most of the flu circulating this season is the H3N2 strain, which historically causes more hospitalizations and deaths among older adults. An early spike in cases, experts say, can heighten risks for this age group. Wolfe noted that when flu season begins unusually early, some nursing homes may still be rolling out vaccinations and some hospitals may not have fully vaccinated their staff. As a result, communities may be less protected than they typically would be if the virus peaked later in the winter.

Overall flu activity remains low, but the CDC’s latest report shows cases climbing. The agency estimates that at least 650,000 people have had the flu so far this season, with around 7,400 hospitalized and 300 deaths reported.

Budd said most of the rise in cases and emergency room visits is occurring in children. Last year, 280 children in the United States died from the flu, marking the deadliest pediatric flu season ever recorded outside the 2009 to 2010 H1N1 pandemic. No pediatric deaths have been reported yet this season, though doctors remain concerned after last winter’s rapid spread of the virus through schools, day care centers and hospitals.

“It feels like the calm before the storm,” said Dr. Buddy Creech, a pediatric infectious disease specialist at Vanderbilt University Medical Center. “We may have a difficult influenza year.”

H3N2 is known for mutating easily, and a new version of the strain, known as subclade K, appeared over the summer with several mutations. It emerged after this season’s flu shot formula had already been finalized and has already driven significant outbreaks in Canada and the United Kingdom.

Budd said the CDC is studying how well the current vaccine matches this evolving strain, but she urged people to get vaccinated regardless. Even when the circulating strain is not a perfect match, she said, the shot still helps reduce the severity of illness.

Doctors across the country are watching the latest trends closely. “Does it turn on our antenna a little bit more? Yes,” said Dr. Daniel Varga, chief physician executive at Hackensack Meridian Health in New Jersey. “It makes us even more vigilant about the monitoring we do locally.”

Dr. Melanie Kitagawa, medical director of the pediatric intensive care unit at Texas Children’s Hospital in Houston, stressed that it is not too late to get vaccinated. She said the more people who receive the flu shot before flu activity accelerates, the better protected communities will be.

Alzheimer’s patients have received discouraging news after the release of results from a major study. Novo Nordisk confirmed that its Alzheimer’s treatment did not show a “statistically significant” slowdown in the progression of the illness. Two trials evaluating the company’s weight loss medicine semaglutide in Alzheimer’s disease did not meet their targets, the firm said on Monday, as the drug failed to slow decline compared with a placebo.

Testing semaglutide, the active ingredient in Ozempic and Wegovy, for Alzheimer’s had always been viewed as a high-risk attempt, even though research has suggested the drug may influence several processes beyond metabolism. Still, Novo had raised interest in recent weeks by advertising roles connected to Alzheimer’s consumer marketing and medical affairs.

Novo Nordisk Says Alzheimer's Drug Trial Fails

Novo Nordisk said on Monday that an older oral form of semaglutide did not achieve its main outcome in late-stage trials assessing whether the drug could reduce cognitive decline in people with Alzheimer’s disease, sending its shares down by 10 percent.

The development dims expectations that Alzheimer’s could become a major new area for GLP-1 medicines like semaglutide, at a time when Novo is facing stronger competition for its leading products in obesity and diabetes. Treatment choices for Alzheimer’s patients remain limited. The company’s study had been closely followed as a potential sign of whether GLP-1 drugs, widely used for diabetes and weight control, might slow the condition’s advance.

The pill tested was Rybelsus, approved only for type 2 diabetes and containing semaglutide, as reported by Reuters.

Novo Nordisk: Lottery Ticket Fails

The firm’s Executive Vice President for Product and Portfolio Strategy, Ludovic Helfgott, had earlier described the Alzheimer’s trials as a “lottery ticket,” reflecting both the uncertainty and the considerable promise involved. Alzheimer’s and related dementias affect more than 55 million people worldwide, and no cure exists. “While semaglutide did not demonstrate efficacy in slowing the progression of Alzheimer’s disease, the extensive body of evidence supporting semaglutide continues to provide benefits for individuals with type 2 diabetes, obesity, and related comorbidities,” Chief Scientific Officer Martin Holst Lange said in a statement.

The findings from the two early-stage studies, EVOKE and EVOKE+, mark another setback for the Danish company and its new CEO Mike Doustdar. Novo had experienced remarkable success with Ozempic and Wegovy, but slower sales growth and a sharp drop in its stock value led to a leadership shift and significant job cuts.

The disappointment adds weight to analysts’ doubts about Novo’s Alzheimer’s plans, with UBS having earlier estimated only a 10 percent likelihood of success.

Novo Nordisk: Alzheimer’s Trial Stakes And Outcome

Alzheimer’s, marked by deep cognitive decline, fading memory and changes in behaviour, remains one of the hardest challenges in drug research. Novo had repeatedly acknowledged the uncertainty surrounding these studies. Even so, the possible payoff was significant. Analysts at Morgan Stanley had estimated that a breakthrough could have added up to $5 billion in yearly revenue.

“We believed it was important to assess whether semaglutide could offer any benefit,” Chief Scientific Officer Martin Holst Lange said, referring to the drug better known as Ozempic. The treatment did show improvement in certain biological markers connected to Alzheimer’s, but these gains did not lead to a slower progression of the condition.

Novo Nordisk Stock: Impact On Competition And Obesity Market

The company is also working to strengthen its footing in the obesity sector. Any sign that Wegovy could influence the most common form of dementia might have provided an edge over Eli Lilly’s Zepbound in the United States, where competition in this field is intensifying.
