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.
Brain cancer that originates in the brain is called a primary brain tumour. It can spread and destroy nearby parts of the brain. Cancers of the breast, lung, skin, or blood cells (leukemia or lymphoma) can also spread (metastasize) to the brain, causing metastatic brain cancer.
