Immune cells that fight cancer become exhausted within hours of first encountering tumors – new research
A type of T cell called cytotoxic T cells can recognize the mutated proteins on cancer cells and should therefore be able to kill them. However, in most patients, cancer cells grow unchecked despite the presence of T cells.
The current explanation scientists have as to why T cells fail to eliminate cancer cells is because they become “exhausted.” The idea is that T cells initially function well when they first face off against cancer cells, but gradually lose their ability to kill the cancer cells after repeated encounters.
Women treated for breast cancer may age faster than cancer-free women
Among women diagnosed with breast cancer, the association with faster biological aging was most pronounced for those who received radiation therapy, while surgery showed no association with biological aging.
Aspartame: popular sweetener could be classified as a possible carcinogen by WHO – but there’s no cause for panic
So far, the regulators have all agreed that it’s safe for a person to consume 40mg of aspartame per kilogram of their body weight per day. That’s about 2.8g for a 70kg adult – and is much more than most people consume.
Pancreatic cancer: a personalised mRNA vaccine may boost effects of treatment
Half of the patients treated with the vaccine and immunotherapy combination saw an increase in a specific type of immune cell (called a T cell, which is known to protect against cancer).
The FDA’s rule change requiring providers to inform women about breast density could lead to a flurry of questions
Breast density matters for two reasons. Most importantly, dense breast tissue can hide cancer on a mammogram. About 40% of breast cancers will go unseen on mammography in the densest breasts, labeled “extremely dense breasts,” and about 25% will go undetected in heterogeneously dense breasts.
Breast cancer: progestogen-only and combined birth control both increase risk – here’s what you need to know
Until now, it was thought that only the combined hormonal pill carried a greater risk of breast cancer. But a recent study suggests that the progestogen-only pill (also known as the mini pill) and other forms of hormonal contraception also carry the same increase in breast cancer risk as the combined pill.
Seattle group reports TB vaccine advance
Temperature-stable TB vaccine is safe and provokes immune response By Brian Doctrow, Ph.D., National Institutes of Health. An experimental tuberculosis vaccine that can be stored at room temperature was safe and provoked an immune response in a Phase 1 clinical…
Turning 50? Here are 4 things you can do to improve your health and well-being
There are four things in particular that take on greater importance when you turn 50 – that go beyond general health advice that’s beneficial at any age, like staying active, eating well and getting enough sleep.
Lung cancer rates have risen among nonsmokers and young women — why?
The American Lung Association reports that while lung cancer rates have risen by 79% for women over the last 44 years, they decreased by 43% for men. And for the first time in history, there are more young women than men diagnosed with lung cancer.
Alcohol use is widely accepted, but even moderate consumption is associated with many harmful effects
Research increasingly shows that the dangers of alcohol have been downplayed and its benefits exaggerated. In fact, having even one drink a day can have a negative effect on your health.
With Stool Testing, Fewer Americans May Delay Colon Screening
For the U.S. health system broadly, and for uninsured patients in particular, stool tests are significantly less costly than colonoscopies. Stool tests are also less time-consuming and invasive.
A blood test that screens for multiple cancers at once promises to boost early detection
Testing to look for circulating tumor DNA in the blood is not new. These liquid biopsies – a fancy way of saying blood tests – are already widely used for patients with advanced-stage cancer. Doctors use these blood tests to look for mutations in the tumor DNA that help guide treatment.
After breast cancer: 5 changes you can make to stay healthy
So, what can you do to improve your chances of living a longer, healthier life after a breast cancer diagnosis?
Pace as important as 10,000 steps for health, studies find
“The take-home message here is that for protective health benefits people could not only ideally aim for 10,000 steps a day but also aim to walk faster.”
In America, Cancer Patients Endure Debt on Top of Disease
Cancer kills about 600,000 people in the U.S. every year, making it a leading cause of death. Many more survive it, because of breakthroughs in medicines and therapies. But the high costs of modern-day care have left millions with a devastating financial burden. That’s forced patients and their families to make gut-wrenching sacrifices even as they confront a grave illness.
