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.

Women who are conflicted while choosing between an injectable contraceptive, a copper intrauterine device (IUD) or a hormonal implant may not need to worry about its impact on human papillomavirus (HPV).
HPV is one of the most common sexually transmitted infections worldwide. While many HPV infections go away on their own without causing problems, some high-risk types can persist and increase the risk of cervical cancer in the long run.
Before this study, scientists debated whether hormonal contraceptives could affect a woman's immune response, making it easier to contract HPV or harder for the body to clear the infection.
According to a new study published in The Lancet Regional Health – Africa, your choice of contraception may not have an impact on the risk of contracting HPV.
Researchers found that women using a commonly used injectable contraceptive known as depot medroxyprogesterone acetate (DMPA-IM), copper IUDs, and levonorgestrel implants had similar chances of contracting HPV and clearing existing infections.

The researchers examined data from women who participated in the large ECHO (Evidence for Contraceptive Options and HIV Outcomes) clinical trial. Participants were randomly assigned to one of three contraceptive methods:
They then compared how often women acquired HPV during the study and how often those who already had HPV were able to clear the infection naturally. The analysis found no meaningful differences between the three contraceptive methods.
Women using the injectable contraceptive were no more likely to acquire HPV than those using a copper IUD or a hormonal implant. Similarly, women across all three groups cleared HPV infections at comparable rates.

Earlier studies finding the link between hormonal contraceptives and HPV have reported mixed results. Some suggested that hormonal birth control might increase the risk of HPV infection or make infections last longer, while others found no clear outcomes.
This new research provides stronger evidence because it is based on a randomized clinical trial. The findings suggest that the type of contraceptive a woman chooses is unlikely to have an impact on her risk of getting HPV or her body's ability to clear the infection.
The study allows women to choose between these commonly used contraceptive methods based on factors such as effectiveness, convenience, side effects, and personal preference, rather than concerns about HPV risk.
However, experts stress that no contraceptive method protects against sexually transmitted infections, including HPV. Using condoms can help reduce the risk of HPV and other STIs.
The human papillomavirus causes more than 200 known infections. While some types lead to benign skin warts, others are responsible for severe health threats, such as cervical, throat, anal, and penile cancers. The HPV vaccine provides strong protection against the most lethal strains, avoiding long-term health complications.
The HPV vaccine helps the immune system recognize and fight off high-risk strains of the virus before they cause harm. It protects against:
Experts also stress that HPV vaccination and regular cervical cancer screening remain the most effective ways to prevent cervical cancer and detect abnormal changes early.

People in the UK can, from today, access the Wegovy weight loss pill through pharmacies with a doctor's prescription. It is the first oral glucagon-like peptide-1 (GLP-1) medicine approved in the UK for weight loss.
The Medicines and Healthcare products Regulatory Agency (MHRA) approved the tablet on June 11, marking the first oral GLP-1 treatment available in the country for obesity management.
"Having met the MHRA's rigorous standards of safety, quality and effectiveness, the semaglutide tablet has been approved in the UK for weight loss and weight management," Julian Beach, Executive Director of Healthcare Quality and Access at the MHRA, said in a statement.
"As with all GLP-1 receptor agonists, this is a prescription-only medication," Beach added.
Novo Nordisk called it an "important milestone for obesity care in the UK".
"For the first time, people living with obesity have access to a GLP-1 treatment in a daily pill, allowing them the choice and flexibility of oral treatment to support their long-term weight management," said Sebnem Avsar Tuna, General Manager at Novo Nordisk UK.

Patients are advised to carefully follow the instructions in the Patient Information Leaflet.
Semaglutide is a GLP-1 receptor agonist that mimics the action of the naturally occurring GLP-1 hormone released after eating.
It acts on areas of the brain that regulate appetite by:
Not yet. Although the medicine has received MHRA approval, it is not currently available through the NHS.
The MHRA said NHS availability will depend on the usual evaluation process by the National Institute for Health and Care Excellence (NICE).
NICE said Novo Nordisk has not yet formally approached it, but that it is in active discussions with the company, BBC reported.
The most commonly reported side effects are gastrointestinal and include:
The MHRA said it will continue to monitor the medicine's safety and effectiveness. Anyone experiencing side effects should speak to their doctor, pharmacist, or nurse and report them through the MHRA Yellow Card scheme.
Community pharmacies say they are preparing for a surge in demand following the launch. The National Pharmacy Association (NPA) urged patients to obtain the medicine only from regulated pharmacies following a proper clinical consultation.

The Democratic Republic of the Congo (DRC) is battling one of its deadliest Ebola outbreaks in recent years. While it is driving innovation in medical science with new clinical trials and diagnostic tests, it is also a stark reminder of the urgency to contain the outbreak as soon as possible.
According to the latest data, the death toll in DRC has now crossed 500 with at least 1,528 cases that are reported and confirmed.
While Ebola is not a new disease, the current outbreak stands apart because it is being caused by a rare strain of the virus, Bundibugyo.
Unlike previous outbreaks dominated by the Zaire strain of Ebola, the current epidemic, caused by the Bundibugyo virus, is a much less common species of the Ebola virus family.
The rarity of the strain has created unique scientific and emergency public health challenges, as there is currently no licensed vaccine designed to protect against Bundibugyo Ebola virus.
During outbreaks caused by the Zaire strain, vaccination became an important part of outbreak control. In the current epidemic, however, public health officials are being forced to rely heavily on rapid diagnosis, infection prevention, surveillance, and existing medical care.

In a major scientific breakthrough, the World Health Organization (WHO) recently added the first molecular diagnostic test for the Bundibugyo Ebola virus to its Emergency Use Listing (EUL).
The test detects the virus's genetic material in blood samples, enabling laboratories to confirm infections more quickly and accurately.
WHO and its partners have launched the first clinical trial specifically evaluating treatments for Bundibugyo Ebola virus disease.
Researchers are testing the experimental monoclonal antibody MBP134, the antiviral drug remdesivir, and a combination of both to determine whether they can improve survival.
The Bundibugyo virus was first identified in Uganda in 2007 and has caused only a few outbreaks since then. As infections have been relatively uncommon compared to the Zaire strain, researchers have had limited opportunities to develop vaccines, treatments and diagnostic tests.
Due to this, healthcare workers have been compelled to rely primarily on rapid isolation of patients, intensive supportive care, contact tracing, and strict infection prevention measures to slow transmission.
Currently, Eastern DRC is the hotspot for the Bundibugyo Ebola outbreak, where conflict, population displacement, skepticism, and insecurity have made it difficult for health workers to reach affected locations.
Here, access to healthcare still remains uneven in many areas. Additionally, movement of people across districts and states in the country can accelerate the spread of infection significantly.
As scientists race to validate new diagnostics and evaluate experimental treatments, the Bundibugyo outbreak is becoming more than a public health emergency. It is also serving as a critical test of how quickly the global health community can develop and deploy new tools against an emerging infectious disease.
