For the first time in 12,000 years, the Ethiopian Hayli Gubbi volcano has erupted. The volcanic plumes has already traveled thousands of kilometer to India and has reached altitudes between 25,000 and 45,000 feet. It has affected Delhi-NCR, Gujarat, Punjab, and Rajasthan, and several other parts of North India. As per the reports, the speed at which the plumes are travelling is at nearly 100 to 120 km/hour at altitudes above 10 km. The plumes contains volcanic ash, sulphur dioxide, and small particles of glass and rock.
Amid Delhi's continuously worsening air pollution, the question rises whether the plumes and the chemicals it contains will impact Delhi's air and the air quality.
The volcanic plumes reached Delhi around 11pm, confirmed the India Meteorological Department (IMD). As per News 18, some residents noticed an unusually diffused, cloud-like haze. However, IMD Director General M Mohapatra said that any significant deterioration in Delhi's air quality is unlikely.
Mohapatra explained that the ash is circulating at high altitudes, which is well above where Delhi's pollution typically concentrates. “It is unclear whether it will impact air quality, but any significant impact is unlikely as it is at higher levels," because plume is in the "upper levels". The Director General noted that there will only be a "marginal rise in temperature" as the ash could behave like cloud cover and absorb and re-radiate heat. However, in terms of Delhi's air quality, he noted that any influence near the ground would be "marginal".
However, the volcanic plumes have impacted flight operations in and around the Indian airspace. Airlines cancelled flights, with IndiGo grounding six flights. Akasa Air said its flights to and from Jedda, Kuwait, and Abu Dhabi scheduled for today and November 24 have been cancelled. KLM Royal Dutch Airplines too cancelled its Amsterdam-Delhi and return flights. IndiGo on X said, "Following the recent eruption of the #HayliGubbi volcano in #Ethiopia, ash clouds are reported to be drifting towards parts of western India. We understand that such news may cause concern, and we want to reassure you that your safety remains our highest priority".
The plumes are expected to head towards China next. It is expected to leave India by 14:00 GMT (7:30 pm local time) on Tuesday.
As per the Centers for Disease Control and Prevention (CDC), volcanoes are geographical formations where lava, small rocks, and steam are released onto the surface of the earth.
When a volcano erupts, it can release harmful particles, including volcanic gases and ash, into the air. These volcanic gases may have an adverse impact on your health, including:
As per the USDA Food and Safety Inspection Service, CO2 is colorless, odorless, non-flammable gas that naturally occurs in the atmosphere. As the CDC mentions, it is also released when a volcanic eruption takes place. CO2 is considered to be minimally toxic by inhalation. The primary health effects caused by CO2 are the result of its behavior as a simple asphyxiant.
A simple asphyxiant is a gas which reduces or displaces the normal oxygen in breathing air.
Symptoms of mild CO2 exposure may include headache and drowsiness. At higher levels, rapid breathing, confusion, increased cardiac output, elevated blood pressure, and increased arrhythmias may occur. Breathing oxygen-depleted air caused by extreme CO2 concentrations can lead to death by suffocation.
As per the National Park Service, Sulfur dioxide is a colorless, reactive air pollutant with a strong odor. This gas can be a threat to human, animal and plant health.
It can irritate the skin and mucous membranes of the eyes, nose, throat, and lungs. High concentrations of SO2 can also cause inflammation and irritation of the respiratory system. This can then lead to pain when taking deep breaths, coughing, throat irritation and breathing difficulties. This gas can further affect lung function, worsen asthma attacks, and exacerbate existing heart diseases.
As per the CDC, hydrogen chloride is a colorless to slightly yellow gas with a pungent odor. On exposure to air, the gas forms dense white vapors due to condensation with atmospheric moisture.
Upon inhalation, the odor could irritate and affect the lungs. While it cannot be absorbed through the skin, its direct contact could irritate the skin and cause chemical burns. The ingestion could also lead to corrosive injury to the lips, mouth, throat, esophagus, and stomach.
As per the US Department of Labor, hydrogen sulfide causes a wide range of health effects, especially if you breathe it and are exposed to it for a longer duration. Its exposure to very high concentrations could also lead to death.
It is a highly flammable, explosive gas, and can cause a life-threatening situation when not handled properly. Its exposure to skin can cause "blue skin" or frostbite.
As per the US Environmental Protection Agency, radon could lead to lung cancer. It is also the number one cause of lung cancer among non-smokers.
As per the CDC, it is also a colorless gas or liquid that could cause severe damage to the body. The effects could also depend on how long one is exposed to the gas. If it is breathed in, it can irritate the eyes and respiratory tract. Breathing in a large amount could cause death from irregular heartbeat or from fluid buildup in the lungs. It can also cause rash and deep, slow-healing burns.
As per the Department of Climate Change, Energy, the Environment and Water run by the Australian Government, sulfuric acid is the world's largest volume industrial chemical. It is corrosive in nature and can severely burn the skin and eyes. It can also cause third-degree burns and blindness on contact. It can also irritate the eyes, nose, throat, and lungs.

The American Heart Association (AHA), in its latest update on nutrition guidance, has urged the need to eat a diet rich in vegetables and fruits, while also making a key shift to plant-based protein from meat-based protein earlier to improve heart health.
It has also emphasized the need to reduce the intake of sugar, salt and ultra-processed foods, as well as to switch to low-fat dairy.
The scientific statement, which is issued about every five years, comes amid increasing cases of high blood pressure and obesity in the US, which can potentially lead to poor health outcomes, including deaths from cardiovascular disease and other chronic conditions.
“For healthy eating to be more attainable and sustainable, we recommend people focus on their overall eating pattern rather than specific nutrients or foods. This approach is actionable, something that can be modified as people pass through different life stages, while still adhering to the nine key features,” said Alice H. Lichtenstein, volunteer chair of the scientific statement writing committee and senior scientist.
“The guidance applies to wherever you eat: at home, school, work, restaurants, or in your community. You want to strive for progress rather than perfection. Every time you choose to make a swap for a healthier alternative, you’re making a step toward a healthier life,” added Lichtenstein, who is also senior scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston.
The 9 Guidelines for a heart-healthy dietary pattern include:

The 2026 guidance for children recommends a heart‑healthy dietary pattern starting at 1 year of age. It urges families to play a significant role and become role models.
“Cardiovascular disease begins early in life; even prenatal factors can contribute to increased risk in children as they grow. So, it’s important that healthy eating patterns are adopted in childhood and continue throughout the entire lifespan,” Lichtenstein said.
“The best way to do that is for adults to role model heart-healthy eating patterns inside and outside the home,” she added.

Breast cancer treatment has evolved significantly over the past few decades, moving from radical removal approaches to more personalized and tissue-preserving techniques. Today, surgeons no longer view breast conservation surgery (BCS) and mastectomy as competing options, but as equally effective strategies chosen based on individual patient needs.
With the growing availability of reconstructive surgery in Kolkata, patients now also have better cosmetic and psychological outcomes regardless of the surgical path they choose.
When faced with a breast cancer diagnosis, understanding the available surgical options is crucial for making an informed decision. Each approach is designed to effectively treat the disease while considering the patient’s long-term health, comfort, and quality of life.
Breast conservation surgery, or lumpectomy or partial mastectomy, is a procedure that involves the removal of the tumor and a small amount of surrounding healthy tissue while preserving most of the breast.
The main objective is to remove cancer without altering the natural shape and appearance of the breast. Radiation therapy is usually administered after surgery to kill any remaining cancer cells and minimize the chances of recurrence.
Mastectomy is the removal of the whole breast tissue, and in other cases, the lymph nodes and skin around the breast. It can be done on either breast or both breasts based on the type of cancer and risk factors.
After a mastectomy, patients can choose to have breast reconstruction with the help of modern surgical procedures, such as those provided in reconstructive surgery in Kolkata, which can help to restore the shape and symmetry of the breast.
The basic distinction is the degree of tissue excision. BCS leaves the majority of the breast, but a mastectomy takes away all of it.
| Factor | Breast Conservation Surgery (BCS) | Mastectomy |
| Extent of Surgery | Removes tumor with a small margin of healthy tissue | Removes entire breast tissue |
| Invasiveness | Less invasive | More extensive surgery |
| Cosmetic Outcome | Preserves most of the natural breast shape | The breast is removed (reconstruction may be needed) |
| Recovery Time | Generally faster recovery | Longer recovery period |
| Radiation Therapy | Usually required after surgery | May or may not be required |
| Risk of Recurrence | Slightly higher local recurrence risk | Lower local recurrence risk |
| Hospital Stay | Often shorter or a day-care procedure | May require a longer hospital stay |
| Suitability | Early-stage cancer, smaller tumors | Larger tumors, multiple areas, or high-risk cases |
| Impact on Body Image | Better preservation of body image | May impact body image (can be improved with reconstruction) |
Notably, several studies indicate that both methods have equal chances of survival in the long term in early-stage breast cancer.
Not every patient is suited for the same surgical approach, as the choice largely depends on individual clinical factors. Tumor size, stage, location, and overall health all play a crucial role in determining eligibility. Understanding who can opt for which procedure helps ensure both effective treatment and optimal long-term outcomes.
Candidates for Breast Conservation Surgery
BCS is usually prescribed to patients with:
It might not apply to patients who have more than one tumor in other parts of the breast or those with advanced disease.
Candidates for Mastectomy
Mastectomy may be suggested when:
Moreover, other patients might opt to undergo mastectomy to have a sense of security or to alleviate the fear of recurrence.
The current surgical advances have greatly enhanced the results, particularly in patients who want to preserve their breasts.
Oncoplastic Surgery
Among the most remarkable developments is the oncoplastic breast surgery that involves the use of both cancer resection and plastic surgery. This enables the surgeons to excise bigger tumors without altering the shape and symmetry of the breast.
This has increased the eligibility of BCS so that more women can avoid mastectomy and still have safe control of cancer.
Improved Imaging and Targeting
Modern imaging techniques have assisted surgeons in accurately identifying tumors so that they can be fully removed without damaging normal tissue. This enhances cosmetic outcomes as well as oncological safety.
Advanced Reconstruction Methods
The emergence of reconstructive surgery in Kolkata has given patients who have undergone mastectomy the opportunity to have an immediate or delayed reconstruction with the help of implants or autologous tissue.
Reconstruction has been brought to improve psychological well-being, body image, and quality of life.
Influencing Factors of Surgical Decision-Making
The decision to use BCS or mastectomy is not only a medical choice, but a very personal one, which depends on several factors:
1. Cancer Stage and Tumor Characteristics
The main determinants include tumor size, location, and spread. BCS is more appropriate in early-stage cancers, whereas mastectomy is usually necessary in advanced cases.
2. Survival and Recurrence Outcomes
It has always been demonstrated that the survival rates are the same with BCS (including radiation) and mastectomy in the case of early-stage cancers. Nevertheless, BCS can be slightly more likely to recur locally, which can be treated.
3. Patient Preference
A major role is played by emotional and psychological factors. There are those patients who want to keep their breasts, and others opt to undergo a mastectomy to have peace of mind. Studies show fear of recurrence is a major driver for choosing mastectomy.
4. Access to Radiation Therapy
Since BCS requires post-operative radiation, access to treatment facilities can influence the decision. Patients without easy access may opt for a mastectomy.
5. Cosmetic and Quality-of-Life Concerns
BCS tends to provide superior cosmetic results and satisfaction. Nevertheless, the modern methods of reconstruction have also helped to enhance the results of mastectomy patients considerably.
Modern breast surgeons support a multidisciplinary patient-centered approach. Instead of prescribing a single solution, they consider:
Surgeons are increasingly preferring breast conservation surgery in most of the early-stage cases because of its good results and quality-of-life advantages. Nevertheless, mastectomy is necessary in more complicated or risky cases.
Conclusion
The debate between breast conservation surgery and mastectomy is no longer about which is superior, but about which is most appropriate for the individual patient. Oncoplastic techniques and reconstructive surgery in Kolkata have advanced, and patients now have a choice of safer, more personalized, and cosmetically satisfying options.

Heart failure has quietly emerged as one of India’s most serious and underestimated health challenges, driven by a rise in hypertension, diabetes, obesity, and delayed diagnosis of heart disease.
Due to a shortage of donor organs and a long waiting period before receiving the right treatment, end-stage heart failure patients in India faced a lot of difficulties a few years ago.
Today, advancements in heart transplant techniques are changing the situation from what was once an untreatable condition to a second chance at life.
Data from the National Organ and Tissue Transplant Organization (NOTTO) shows a significant year-on-year rise in heart transplants, with 253 transplants done in 2024, showcasing improved organ donation awareness, better coordination between hospitals, and stronger transplant networks.
What was once considered the only option is now emerging as a life-saving solution, offering patients not just a second chance but a return to a more meaningful and active life.
A heart transplant offers hope and gives a second life to patients whose hearts no longer support the body even after the best available medical aid.
Although it is never performed instantly, it becomes necessary whenever conditions of the heart result in end-stage heart failure, where the pumping function of the heart is compromised.

When medications and modern technologies cannot supply an adequate amount of blood and oxygen to the organs, patients experience extreme breathlessness, fluid buildup, fatigue, and repeated hospitalizations, making even simple activities like walking, eating, or lying flat exhausting.
As the flow of blood continues to deteriorate, failure is also expected in other vital organs such as the kidneys and liver. It is at this point that the transplantation of the donor heart is considered the only treatment option to ensure that the blood flow is normalized.
Heart transplant is not just a surgical replacement of a failing organ, but a complete life restoration for patients with end-stage heart failure.
Its benefits include:
