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.
Cancer begins when a cell begins dividing uncontrollably. Eventually these cells form a visible mass or tumor. This initial tumor is called the primary tumor. Cells from the primary tumor can break off and lodge elsewhere in the body where they then grow into secondary tumors. This process is called metastasis and a cancer which has spread to other organs is called metastatic.. When cancer spreads to another organ, the type of cancer remains the type of the primary tumor. Thus cancer that started in the colon and spread to the liver is still colon cancer. It is not liver cancer.
