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.

A 25-year-old Spanish woman has died by euthanasia after a long battle with her father over her right to die.

Noelia Castillo, a rape survivor who was left paralyzed in her lower half of the body after a suicide attempt in 2022, died on Thursday evening at a hospital in Barcelona.

While the Catalan regional government had granted her the right to assisted dying in 2024, her father, Geronimo Castillo, had raised legal objections. Her wish to ‘die in peace’ has also sparked debate around the country’s right-to-die law -- legalized in 2021.

Who Is Noelia Castillo?

Much of Castillo’s life during her childhood was spent in care homes. Her father's problems with alcohol had a significant impact on her mental health, and she underwent psychiatric treatment since her early teens.

Later, she was diagnosed with conditions including obsessive-compulsive disorder and Borderline Personality Disorder.

She was raped twice: first by an ex-boyfriend and later by three men in 2022 while at a state-supervised facility for vulnerable youth.

The assaults, which took a severe toll on her mental health, led her to make multiple suicide attempts.

In October 2022, she jumped from a fifth-floor window, which left her with a severe spinal cord injury and permanent paralysis in her lower body.

Noelia Castillo’s Fight For Euthanasia

Castillo chose assisted dying to escape years of physical pain and emotional trauma.

In her final days, Castillo spoke openly about her suffering and her decision. In an interview with Spanish broadcaster Antena 3, she said: “I just cannot go on anymore… I want to go in peace now and stop suffering.”

Speaking earlier to Spanish TV programme Y Ahora Sonsoles, she added: “I am very clear… none of my family is in favour of euthanasia. But what about all the pain I’ve suffered during all these years?”

In 2024, the Catalan regional government granted her the right to assisted dying in 2024. But the process was suspended after legal objections raised by her father. According to her father, her mental health did not allow her to make better decisions about herself.

Noelia Castillo: 18-month-long Legal Battle

Christian Lawyers (Abogados Cristianos) had been attempting to block her death until the last moment. For 18 months, the case moved through multiple courts, eventually reaching Spain’s Constitutional Court, which ruled there was “no violation of fundamental rights” in allowing her euthanasia.

Finally, the European Court of Human Rights (ECHR) ruled this week in Noelia Castillo's favour, and her death was eventually confirmed late on Thursday.

In a TV interview this week, she said nobody in her family had supported her decision to die by euthanasia, and her father "hasn't respected my decision and never will".

"I want to go in peace now and stop suffering," she told Antena 3 TV the day before she died.

Critics Call Her Death A Failure Of The State

"For a girl who obviously has had a very tough life, which we all regret, the only thing that could be offered to her by the healthcare system is death," said José María Fernández, of Christian Lawyers.

The opposition conservative People's Party (PP), which voted against a 2021 euthanasia law, had a similar response.

Several senior Catholic leaders in Spain have sharply criticised the euthanasia of 25-year-old Noelia Castillo, calling it a reflection of societal failure and raising concerns over the country’s right-to-die law.“We have all failed as a society,” Jose Mazuelos Perez, Bishop of the Canary Islands, was quoted as saying by EuroNews.

In a joint statement, church leaders said the case reflected “an accumulation of personal suffering and institutional shortcomings”.

The BA.3.2 COVID-19 variant, nicknamed Cicada, is evading capable antibodies gained from previous vaccinations. According to experts, it is less likely that the currently available COVID vaccines will provide protection.

As per the US Centers for Disease Control and Prevention (CDC), Cicada — a highly mutated variant of COVID — has already been reported in at least 23 countries, including 25 states in America. It has also been detected in 132 wastewater samples from Massachusetts.

What Is The Cicada COVID Variant?

Cicada was first identified in a respiratory sample in South Africa in November 2024.

It is a descendant of the Omicron BA.3 lineage, and is genetically distinct from the previously circulating JN.1 lineages (including LP.8.1 and XFG).

BA.3.2 comprises two major branches, BA.3.2.1 and BA.3.2.2. BA.3.2.2 also has substitutions like: K356T, A575S, R681H, and R1162P.

The World Health Organization (WHO) has designated BA.3.2 as a Variant Under Monitoring (VUM). It means the variant may not be that dangerous yet, but it may have concerning mutations.

The CDC’s latest Morbidity and Mortality Weekly Report explains that Cicada has “70 to 75 substitutions and deletions in the gene sequence of its spike protein”.

Will Current COVID Vaccines Work?

The variant is particularly concerning as it provides no immune protection to people with previous infection or even vaccination.

“The number of mutations from JN.1 viruses makes it less likely that the current vaccines will be highly effective against Cicada, but we need more data to better answer this question,” Dr. Robert H. Hopkins Jr., medical director of the National Foundation for Infectious Diseases, told USA TODAY.

However, according to the WHO, current COVID vaccines are expected to continue protecting against severe disease. Moreover, the WHO said BA.3.2 doesn’t seem to be making people sicker so far and hasn’t resulted in increased hospitalizations and deaths.

“Overall, available evidence suggests that BA.3.2 poses low additional public health risk compared with other circulating Omicron descendant lineages,” WHO said.

And unlike previous strains, BA.3.2 hasn’t rapidly overtaken other variants; in fact, it hasn’t fueled enough cases nationally to land on the CDC’s variant tracker.

“If it had really special advantages, we’d probably have seen it take off and dominate globally relatively quickly,” Andrew Pekosz, a virologist at the Johns Hopkins Bloomberg School of Public Health, told TODAY.com. “We didn’t see that, but it’s not going away, so it’s something to keep an eye on.”

Will Cicada Become The Dominant COVID Strain

Hopkins Jr. expressed the possibility that "Cicada can become the dominant strain in the US”. While it is not certain, it can also "drive a US summer surge.”

The CDC has also warned that a new variant "with substantial capacity to evade immunity from previous infections or vaccines could be associated with seasonal increases in COVID-19 activity.”

What Makes Cicada So Unique?

T Ryan Gregory, a professor of evolutionary biology at the University of Guelph stated that Cicada is emerging as a contender for the next major lineage.

He wrote on social media platform X: "Well, it's that time again. Meet "Cicada", BA.3.2* (including descendant RE.*). This one has been underground for years (its ancestor BA.3 hasn't been circulating since early 2022, and didn't do much then either) but is now emerging as a contender for the next major lineage."

While most of the symptoms of this new variant remain the same as those of the other variants, one thing that stands out here is the gastrointestinal symptoms that cicada could cause.

However, experts note that this variant will not make anyone sicker. Other symptoms include:

• Cough
• Fever or chills
• Sore throat
• Congestion
• Shortness of breath
• Loss of smell or taste
• Fatigue
• Headache.

After a recent Supreme Court of India order banning the use of stem cell therapy to treat autism -- a neurodevelopmental condition affecting communication, social interaction, and behavior -- the country's National Medical Commission has issued a clear warning to doctors and hospitals not to use the therapy to treat autism in routine medical practice.

The National Medical Commission, in a new advisory, asked all medical colleges, hospitals, and doctors to strictly follow the rules.

In a letter sent to the regulator, Indian Council of Medical Research Director-General Dr. Rajiv Bahl stated that the stem cell treatment can now be used in regular medical practice only for 32 diseases that are officially approved by the government. These include blood cancers and serious blood disorders such as:

Acute myeloid leukemia

Thalassemia

Multiple myeloma

Aplastic anemia

Myelofibrosis

Germ cell tumors.

The letter asked doctors not to offer stem cell therapy for any other disease outside this list.

Notably, the Ethics and Medical Registration Board (EMRB), under the National Medical Commission (NMC), had, in December 2022, constituted the Committee on Stem Cell Use in Autism Spectrum Disorder (ASD).

It had stated that none of the current international guidelines recommend stem cell therapy as a treatment for ASD and added that the therapy is not recommended as a treatment for ASD in clinical practice.

What Was The Supreme Court Ruling On Stem Cells?

Earlier this year, in January, a bench comprising Justice JB Pardiwala and Justice R Mahadevan noted that stem cell therapy lacks “scientific support and has not been recognized as a sound medical practice backed by empirical evidence”.

The Bench ruled that “every use of stem cells in patients outside an approved clinical trial is unethical and shall be considered as malpractice.”

The apex Court, however, added that the advanced therapy, which holds promise in several medical fields, can still be approved for monitored clinical research trials. It added that the patients have the liberty to participate in approved and regulated clinical trials.

What Is Stem Cell Therapy

Stem cell therapy, also called regenerative medicine, is a medical treatment that uses stem cells to repair or replace damaged tissues.

While the therapy is useful and effective for blood cancers and autoimmune diseases, for the treatment of autism, there is no proof or scientific evidence of its utility.

As stem cell therapy is vastly unregulated in India, many private labs have been minting money over the promise of treatment for autism.

“Most stem cell therapies are unregulated in India and are promoted based on no evidence, and fake advertisements. While these disorders have no cure, many people are falsely lured by these companies,” Dr. Manjari Tripathi, Head of Department, Neurology, AIIMS Delhi, had told IANS, after the SC verdict.

Stem Cells Permissible Only For Research

The NMC warned that any doctor or institution offering stem cell therapy for autism will face regulatory and legal action.

The top medical regulator, however, stated that stem cell therapy is permissible only for research purposes.

Such studies must follow strict rules set by the government and must be approved by ethics committees and national regulatory bodies.

Researchers must also ensure that patients give written consent, that treatment is provided free during the trial, and compensation is offered if injury or death occurs during research.
