Studies have shown that routine screening mammography does reduce breast cancer deaths in women aged 40 to 75. But screening also comes with downsides, which include the risk of overdiagnosis and overtreatment. A new study suggests that the risk of overdiagnosis with routine screening mammography is substantial for women in their 70s and older.
Skin cancer affects about 6 million Americans yearly, more than all other types of cancers combined.
I understood from my work as cancer doctor that not undergoing treatment was an option. In some cases, that is the better choice. So I took it upon myself to educate my father on his disease and assist him with the life-changing decisions he would have to make. Our journey can give you a preview of what a cancer diagnosis can be like.
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.
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.
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.
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).
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.
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.
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…
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.
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.
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.
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.
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.
