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 are not always reliable for the following reasons: 1  Most tumor markers can be made by normal cells, as well as cancer cells. 2  Tumor markers can be associated with noncancerous conditions. 3  Tumor markers are not always present in early stage cancers. 4  People with cancer may never have elevated tumor markers.
