Stomach cancer (credit: canva)
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.
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.

Kerala is grappling with a triple public health challenge as cases of Shigella infection, West Nile fever, and Nipah virus disease are being reported across the state.
While Kerala has faced outbreaks of all three diseases in the past, their simultaneous occurrence has put health authorities on high alert, prompting intensified surveillance, contact tracing, and disease-control measures. The officials have urged people to remain cautious while avoiding unnecessary fear.
Seven more students recently tested positive for shigellosis in the northern district of Wayanad, taking the total number of confirmed cases to 16.
According to District Medical Officer K.T. Rekha, symptoms have been identified in more than 500 people, most of them children. Around 45 patients are currently undergoing treatment, while 174 people have been admitted to hospitals since the outbreak began.
Health authorities have intensified surveillance, visited more than 2,200 households, chlorinated over 1,300 wells, and distributed ORS packets across the district.
Common symptoms include:
The National Institute of Virology (NIV), Pune, has confirmed Nipah virus infection in a 43-year-old man from Ramanattukara in Kozhikode district.
The patient remains in critical condition on ventilator support at a dedicated Nipah isolation facility in Kozhikode Government Medical College Hospital.
Health officials have identified 77 contacts through tracing efforts:
Early symptoms often resemble common viral illnesses and may include:
Kerala has also reported two deaths linked to West Nile fever in Ernakulam district within a week.
Health officials said the mosquito-borne disease is caused by a flavivirus commonly found in migratory birds and transmitted to humans through infected mosquitoes. The disease does not spread from person to person.
Symptoms can include
The elderly, pregnant women, children, immunocompromised individuals, and people with underlying health conditions are considered at higher risk.
Researchers have suggested that environmental changes, habitat disruption, and increasing interaction between humans and wildlife may be contributing to the repeated emergence of zoonotic diseases in Kerala.
A recent study titled "Two Geographies, One Virus: What Recurrent Nipah Spillover in India Reveals" found that deforestation, habitat loss, and increased human activity in biodiversity-rich regions could create more opportunities for viruses to spill over from animals to humans.
Health experts recommend:
The monsoon season creates favorable conditions for waterborne, foodborne, and mosquito-borne diseases, making vigilance essential for both health authorities and the public.

The ongoing Ebola outbreak in the Democratic Republic of Congo (DRC) continues to expand, with the virus spreading to three new health zones in North Kivu and Ituri provinces, according to government officials.
The country, which is battling its 17th Ebola virus disease outbreak, has now recorded 676 confirmed cases and 136 deaths, Health Minister Dr. Samuel-Roger Kamba said in a post on social media platform X.
Kamba informed that the virus has spread to three new health zones in the country. They are:
Masereka (North Kivu)
Vuhovi (North Kivu)
Kambala (Ituri)
“#EbolaBundibugyo: As of June 10, 676 cumulative confirmed cases — 629 in Ituri, 44 in North Kivu, 3 in South Kivu. Forty-one new cases reported today,” Kamba wrote.
“Three new health zones affected: Masereka and Vuhovi in North Kivu, Kambala in Ituri. Our teams are adapting, surveillance is intensifying. The response follows every signal, in every zone,” he added.

The outbreak, caused by the rare Bundibugyo strain of the Ebola virus, was officially declared on May 15.
There is currently no approved vaccine or specific treatment for this strain.
The minister also reported total 10 recoveries from the deadly disease.
“#EbolaBundibugyo: Two newly recovered today in the Bunia Health Zone. They are returning home. Every recovery is a victory, a message of hope for our communities. Come get treated quickly — early care saves lives,” Kamba said.

Meanwhile, the Ebola outbreak has also disrupted the preparations of the Democratic Republic of Congo national football team ahead of the FIFA World Cup.
The squad arrived in the United States after spending three weeks in isolation in Europe due to the outbreak in their home country. US authorities required the team to complete the quarantine period in Belgium before being allowed to enter the country, AFP news agency reported.
DRC cancelled a planned pre-tournament training camp at home and instead based preparations in Belgium.
In addition, a scheduled warm-up match against Chile in Spain was also cancelled over concerns about the spread of the virus.
“We adapted to the situation,” said head coach Sebastien Desabre. “We had to focus, as we have had to adapt often.
“That is what we did. We worked well, we played two tough friendlies, and here we are. Now, it is another step for us.”
The team will be based in Houston during the tournament and is scheduled to play its opening Group K match against Portugal on June 17.
Ebola is a severe and deadly disease caused by a virus mostly found in Africa. The spread of the disease happens through contact with infected body fluids.
Symptoms includes fever, headache, weakness, vomiting, diarrhea, muscle pain, sore throat, and unexplained bleeding. This eventually leads to severe complications like bleeding, organ failure, and death.
Ebola is a highly lethal viral hemorrhagic fever first identified in 1976. Over the past five decades, it has caused over 30 outbreaks, primarily in Central and West Africa. The virus takes its name from the Ebola River in the Democratic Republic of the Congo (DRC).
Three strains of the virus — Ebola virus, Sudan virus, and Bundibugyo virus — have caused the largest outbreaks in Africa. Among them, the Ebola virus is considered the deadliest, with fatality rates reaching up to 90% without treatment.

Researchers at the Indian Institute of Technology Madras (IIT Madras) have released the world’s most detailed 3D atlas of the human brainstem.
Called ANCHOR (Atlas of Neurochemical Characterization of the Human Brainstem with 3D Reconstruction), the atlas was developed using a high-throughput brain imaging and computing platform that transforms whole human brains into 3D cell-resolution atlases.
It provides comprehensive multi-modal 3D maps of the human brainstem across the lifespan, covering the prenatal period, childhood, and adulthood.
The atlas includes more than 200 brainstem nuclei and fiber tracts reconstructed from hundreds of serial sections. To identify distinct neurochemical cell types, researchers overlaid eight complementary immunostains across more than 500 sections, enabling detailed mapping.
Developed by the Sudha Gopalakrishnan Brain Centre (SGBC) at IIT Madras, ANCHOR has been made publicly available to researchers, clinicians, and patients worldwide.
“This is a significant accomplishment in the field of neurobiology. This is a multimodal framework integrating MRI, histology, and detailed chemo-architecture. It will be the most detailed and comprehensive maps of the human brainstem, and made available publicly in digital form. These maps will help in identifying specific cell populations affected in brain stem lesions, which could be critical for clinical applications,” said Prof. Ajay Kumar Sood, Principal Scientific Adviser to the Government of India, during the 3rd BRICS Neuroscience Symposium 2026.
Prof. Mohanasankar Sivaprakasam, Head of SGBC, IIT Madras, said the atlas uses a multimodal image visualization framework that integrates volumetric MRI data with cellular-level images.
“By establishing precise spatial correspondence across these modalities, the atlas enables a seamless transition from gross brain structures in the MRI to cellular-level features. We envision that these maps and atlases will have significant implications for neuroscience and neuromedicine,” he said.
The human brainstem contains more than 200 nuclei and fiber tracts and plays a vital role in regulating essential body functions.
ANCHOR is an online platform featuring more than 800 serial histological sections stained for Nissl and seven immunochemical (IHC) markers from three human brainstems representing different stages of life:
The atlas also describes catecholaminergic groups across all three age groups, identifies the protoplasmic commissural dendrites of the hypoglossal nucleus, and describes the pretectal nuclei in the fetal brainstem.
