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.
Primary lung tumors account for 50% of all metastatic brain tumors. Lung cancer is the most common origin of metastatic disease. Of lung cancer patients who survive for more than 2 years, 80% will have brain metastases.esticular tumor is a uncommon cancer and yet it more frequently metastasizes to the brain as compared with lung cancer. Patients with brain metastasis at the same time of having systemic cancer (synchronous metastasis) tend to do worse as compared with patients with metachronous metastatic disease.
