Disease-causing organisms do not affect everybody the same way; they are most dangerous to people who have weak immune systems or are frequently sick. Not all bacteria and viruses will make you sick, but this website tells you if the waterbody you are interested in using has problems with disease-causing organisms.
When cancer cells travel to other organs in the body, itâs called metastasis. Metastatic lung cancer is a life-threatening condition that develops when cancer in another area of the body metastasizes, or spreads, to the lung. Cancer that develops at any primary site can form metastatic tumors. These tumors are capable of metastasizing to the lungs.
About one-third of patients with another type of cancer will develop one or more metastatic brain tumors. The most common types of cancer that cause metastatic brain tumors are lung cancer, breast cancer, melanoma (skin cancer), colon cancer, kidney (renal) cancer, and thyroid cancer. The risk for metastatic brain tumors begins to increase in people ages 45 to 65, and is highest in those over 65.
