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.
These substances can be found in the blood, urine, stool, tumor tissue, or other tissues or bodily fluids of some patients with cancer. Most tumor markers are proteins. However, more recently, patterns of gene expression and changes to DNA have also begun to be used as tumor markers.
