Lymph nodes (also called lymph glands) are an important are part of your immune system. If your lymph nodes become enlarged or feel sensitive to the touch, that is their way of letting you know that your body is fighting an infection. In addition to that, they function as an early warning system for some types of cancer, including lymphoma, leukemia, and breast cancer.
Inflammatory breast cancer is a rare but aggressive form of breast cancer. This cancer, which accounts for 1% to 5% of all breast cancer diagnoses in the United States, forms in the cells that line the breasts’ milk ducts, but quickly spreads to nearby lymph nodes and sometimes, to other tissues in the body. The cancer is called “inflammatory” because the cancer cells usually block the lymph vessels in the breast. This blockage causes a buildup of fluid, which then leads to inflammation that is usually red and tender to the touch.
When it comes to cervical cancer, nearly all cases are caused by exposure to the human papillomavirus, or HPV. Thankfully, cervical cancer is almost always preventable. Understanding more about HPV and cervical health, in general, can greatly help in the prevention of this kind of cancer. Here’s some important information every woman should know.
6 ovarian cancer signs and symptoms every woman should know:
Changes in appetite
Bloating or increase in abdominal girth
Changes in menstruation
Discomfort in the pelvis
September is Ovarian Cancer Awareness Month, so it's a good time to learn more about early detection and save lives. About 22,000 women are diagnosed with ovarian cancer each year in the US. While about half of all cases happen in women who are age 63 and older, all women face some risk of developing the disease. Certain risk factors, including being overweight and a history of ovarian cancer in the family, may increase your chances of being diagnosed. Ovarian cancer research clinical trials are underway, but it's still good for patients to be educated about detecting ovarian cancer early.
Only 19% of women are diagnosed in the early stages of this disease. That’s because many symptoms of ovarian cancer could also be signs of less serious medical problems. However, if you notice any of these symptoms for more than 12 days per month and they are new to you, it is time to visit your gynecologist for a checkup:
Cancer researchers from Johns Hopkins have concluded that some patients may develop colon cancer due to two specific digestive bacteria that form a film on the colon. According to the study paper, which was published December 2015 inScience magazine, these two types of bacteria invade the protective mucous layer of the colon and create a small ecosystem, including nutrients the bacteria need to survive, causing chronic inflammation and subsequent DNA damage that supports tumor formation. These findings also seem to add to the growing evidence that gut bacteria is more influential on our immune system than we may realize.
The two bacteria the doctors found are known as Bacteroides fragilis and Escherichia coli (or E. coli). The B. fragilis strain, called ETBF, appears to cause inflammation in the colon, while the E. coli strain causes DNA mutations.
Also, the bacteria was linked to patients without a family history of colon cancer. Cancers such as these--where there is no genetic tie--are known as sporadic cancers. Only 5-10% of cancers are considered heredity, meaning the remaining 90-95% are considered sporadic.
