Cancer is a large group of diseases that can start in almost any organ or tissue of the body when abnormal cells grow uncontrollably, and go beyond their usual boundaries to invade adjoining parts of the body. According to the World Health Organization (WHO), it is the second most common cause of death globally, accounting for millions of deaths every year. Lung, prostate, colorectal, stomach and liver cancer are the most common types of cancer in men, while breast, colorectal, lung, cervical and thyroid cancer are the most common among women. However, these are not necessarily the deadliest forms of cancer.

What makes cancer the deadliest depends upon how many people have it and what percentage of those people actually survive. Cancer researchers determine this on the basis of five-year relative survival. This is the percentage of people who are expected to survive the effects of a given cancer, excluding their risk of other possible causes of death, for five years past a diagnosis. It is also important to note that what makes cancer really deadly is that practically no cure for it. A cure for cancer would imply that there are no cancerous cells remaining in the body.

Here are the 5 deadliest cancers in the U.S., according to SEER five-year relative survival data for cases diagnosed between 2014 and 2020.

1. Pancreatic cancer occurs when cells in your pancreas, a gland in your abdomen that aids digestion, mutate and multiply out of control, forming a tumour. Major risk factors include smoking, obesity, diabetes, chronic pancreatitis, certain genetic mutations and environmental chemical exposure.

2. Esophageal cancer develops in the oesophagus, which is the tube that connects your throat to your stomach.

3. Liver cancer and intrahepatic bile duct cancer originate in the liver or bile ducts, often linked to hepatitis infections, heavy alcohol use, obesity, and aflatoxin exposure.

4. Lung and bronchus cancer primarily caused by smoking, secondhand smoke, and environmental pollutants, affects the lungs and airways, making it the leading cause of cancer death in the US.

5. Acute myeloid leukaemia (AML) is an aggressive blood and bone marrow cancer that progresses rapidly, often linked to genetic mutations, radiation exposure, and certain chemicals.

COVID-19 Is Surging in Parts of California, Wastewater Data Reveals

Updated Aug 16, 2026 | 11:15 AM IST

SummaryA recent observation of wastewater data revealed that COVID-19 is surging in several parts of Bay Area, California. Experts, however, said that there is no reason to panic.

COVID-19 is surging in some parts of California as wastewater surveillance showing a sharp rise in the amount of virus circulating in the surrounding communities.

The latest data comes as California health officials warn that the state’s COVID-19 pattern appears to be shifting, with summer outbreaks becoming more prominent than winter ones.

According to the California Department of Public Health data cited by the San Francisco Chronicle, COVID-19 outbreak expanded in June, rose through July and continued rising in August. Hospital admissions are also increasing, although they remain relatively low compared to previous outbreaks.

WastewaterSCAN data showed that COVID-19 concentrations across monitored Bay Area sites were 136% higher in July than in June. By early August, nearly 54% of monitored sites were classified as having “high” levels, with San Francisco, San Jose, Sunnyvale, San Rafael, Vallejo and Napa among the communities reporting high levels of cases.

“Monitoring wastewater can act as an early warning system for health officials and the public,” said Amanda Bidwell, WastewaterSCAN’s scientific program manager.

Wastewater Surveillance Reveals COVID-19 Resurgence

Wastewater surveillance looks for traces of SARS-CoV-2 in sewage. Because infected people can shed the virus even when they have mild or no symptoms, wastewater can provide an early picture of infections spreading through a community.

The CDC says wastewater trends can detect viruses earlier than clinical testing and can also capture infections that never result in a doctor's visit. An increase in wastewater viral activity may therefore signal a higher risk of infection in the community.

California is currently one of only four U.S. states where COVID-19 wastewater activity is classified as moderate or high by the CDC, according to the Los Angeles Times. The CDC also says COVID-19 is growing or likely growing in 43 states.

Is A Dangerous New COVID Variant Causing The Surge?

Wastewater monitoring suggests several variants are circulating rather than one strain. In the Bay Area, XFG, also known as “Stratus,” remains prominent, while NB.1.8.1, or “Nimbus,” is also circulating.

Stanford infectious disease expert Dr. Abraar Karan said there is currently no evidence suggesting a dangerous or different virus or a variant that is expected to cause a major increase in hospitalizations or causalties.

Experts say the current wave should not be confused with the severe COVID-19 surges of the pandemic's early years. According to recent data and reports, hospitalizations remain comparatively low compared to previous outbreaks.

However, California health officials are urging people who have not received the 2025-26 COVID-19 vaccine to consider getting it now rather than waiting for the updated vaccine expected later this year.

“Summer is really the bigger peak,” California Public Health Officer Dr. Erica Pan said. “Go ahead and get it now, given the surge.”

The timing could become important as schools reopen and people spend more time in crowded indoor settings. In 2025, California's summer COVID-19 wave peaked later in the season, meaning the current increase may not be over yet.

V, a member of K-pop sensation BTS, has revealed that he has been dealing with hearing loss in one ear for about two and a half years.

V, whose real name is Kim Tae-hyung, opened up about the condition for the first time during a livestream amid the band's highly anticipated world tour.

"If the hearing in my left ear is at 100, it's only about 30 in my right," V said.

The 30-year-old singer said his hearing became worse while he was serving in the military. However, he initially ignored the problem, believing it was "a matter of mental strength," BBC reported.

He said he is now taking medication and visiting the hospital regularly.

V Reveals Risk Of Stress Fracture

V also admitted to pushing through pain during BTS' current tour, revealing that he is dangerously close to developing a stress fracture in his leg.

“My shin is right at the point just before a stress fracture. Even today on stage, my heart was set on running around, but it hurt too much at points and I couldn’t," he was quoted as saying by Channel News Asia.

Doctors have warned him about inflammation and early bone damage.

“It hasn’t reached a stress fracture yet, but there’s a lot of inflammation in my shin, and I think there’s some microdamage to the bone. I’ll be careful with myself so I can finish this tour properly,” he added.

BTS is currently halfway through its massive Arirang world tour, which will stop in Singapore in December and conclude in the Philippines in March 2027.

What Is Hearing Loss?

Hearing loss can happen when any part of the ear is not working in the usual way. This includes:

  • The outer ear
  • The middle ear
  • The inner ear
  • The hearing or acoustic nerve
  • The auditory system in the brain
When sound cannot travel properly through these structures, or when the brain cannot process sound clearly, hearing becomes impaired. It may be partial or complete, temporary or permanent, and can occur at any stage of life, from before birth to adulthood.

Hearing loss is a growing health concern worldwide. According to the WHO, more than 1.5 billion people—nearly 20% of the world's population—live with some degree of hearing loss. Of these, approximately 430 million people have disabling hearing loss requiring rehabilitation.

Hearing loss can have a significant impact on a person's life, affecting education and job prospects.

What Causes Hearing Loss?

Hearing loss can occur at any time during life. Causes can range from genetic factors to conditions such as Down syndrome or Usher syndrome.

Other factors include:

  • Maternal infections during pregnancy
  • Complications after birth
  • Spending five days or more in a neonatal intensive care unit (NICU)
  • Severe jaundice requiring a blood transfusion

How To Prevent Hearing Loss

To help prevent hearing loss in adults:

  • Limit exposure to loud noises above 85 decibels.
  • Wear ear protection, such as foam plugs or earmuffs, around heavy machinery or at concerts.
  • Keep personal headphone use at safe volumes.
  • Manage chronic health conditions such as high blood pressure.
  • Avoid putting objects such as cotton swabs inside the ears.

Union Health Minister JP Nadda was admitted to AIIMS Delhi after experiencing uneasiness and underwent tests, including a coronary angiography. The hospital, in a statement, said he is stable and under observation in the cardiology department.

JP Nadda Under Observation

The 65-year-old minister was admitted on August 13 after experiencing uneasiness. He underwent tests, including coronary angiography.

“JP Nadda, Minister of Health and Family Welfare, was evaluated for uneasiness with tests including a coronary angiography on the evening of 13th August 2026. He is currently stable and admitted for observation in the Dept of Cardiology,” AIIMS said in a statement.

Is Uneasiness A Sign Of Heart Problems?

Heart problems do not always cause obvious symptoms. While common symptoms include chest pain or pressure, palpitations, and breathing difficulties, reduced blood flow to the heart can sometimes present with subtle signs or no symptoms.

Possible warning signs include:

  • Unusual fatigue
  • Shortness of breath
  • Jaw pain
  • Irregular heartbeat
  • Swollen feet and ankles
  • Dizziness
  • Cough
  • Leg pain or cramps
  • Poor sleep

What Is Coronary Angiography?

Coronary angiography is a test used to check the blood vessels supplying the heart for narrowing or blockages.

A thin catheter is usually inserted through an artery in the wrist or groin. Contrast dye is injected, and X-rays are used to visualize the coronary arteries.

Why Is It Done?

Doctors may recommend coronary angiography for:

  • Unexplained chest pain
  • Abnormal results from tests such as an ECG, stress test or echocardiogram
  • A heart attack, to locate a blocked artery
  • Unexplained heart failure or cardiac arrest
  • Certain congenital heart conditions

Why Are Heart Checkups Important?

Regular checkups can help detect heart disease early and monitor risk factors such as:

  • Blood pressure
  • Cholesterol
  • Blood sugar
Early detection can also support preventive measures, including a healthy diet, regular exercise and stress management.

Who Should Consider Regular Heart Checkups?

Regular monitoring can help detect changes early and support timely action to reduce long-term cardiovascular risk.

Regular heart checkups are particularly important for people who:

  • Are above 30
  • Have a family history of heart disease
  • Have high blood pressure, diabetes or high cholesterol
  • Smoke or frequently consume alcohol
  • Lead a sedentary lifestyle
  • Are overweight or obese
  • Experience ongoing stress

Common Tests Included In A Heart Checkup

Depending on individual risk factors, a heart checkup may include:

  • Blood pressure measurement
  • Blood tests for cholesterol, triglycerides and blood sugar
  • ECG to assess heart rhythm
  • Echocardiography to assess heart structure and function
  • TMT or stress test to assess the heart during exertion

Additional tests, such as CT coronary angiography or specialized cardiac biomarkers, may be recommended in some cases.
