Today, the IOM liberally recommends an even higher volume of total daily water intake: 3.7 liters (15 cups) for the average adult male and 2.7 liters (11 cups) for the average adult female. If these numbers seem daunting, donât worry.
There are two types of tumors: malignant (ma-LIG-nant), or cancerous, tumors are made up of abnormally shaped cells that grow quickly, invade nearby healthy tissues, and often make their way into the bloodstream. When these cells travel to other parts of the body, they form additional tumors.
Researchers look for a genetic source of childhood tumors. Germ cell tumors (GCTs) are masses of tissue formed by the type of immature cells which, in a healthy body, would develop into mature eggs (in a female) or sperm (in a male). Germ cell tumors may be malignant, which means cancerous, or they may be benign, which means noncancerous.
