Infants need about 100 mL of water/kg body weight per day, so a 5 kg infant needs about 500 mL and a 10 kg infant needs about 1 liter (3) . Healthy breastfed infants can get all the water they need with the motherâs milkâ assuming their mothers produces enough milk, which all healthy mothers should.
Tumor markers are measurable biochemicals that are associated with a malignancy. They are either produced by tumor cells (tumor-derived) or by the body in response to tumor cells (tumor-associated). They are typically substances that are released into the circulation and thus measured in the blood.
Tumor markers may also be measured periodically during cancer therapy. A decrease in the level of a tumor marker or a return to the markerâs normal level may indicate that the cancer is responding to treatment, whereas no change or an increase may indicate that the cancer is not responding.here is no âuniversalâ tumor marker that can detect any type of cancer. There are some limitations to the use of tumor markers. Sometimes, noncancerous conditions can cause the levels of certain tumor markers to increase.
