4. Swollen Glands
Since leukemia has a damaging effect on the blood, it is much more difficult for the body to fight off opportunistic infections and that can cause glands and lymph nodes to swell. This can manifest as small lumps or bumps that show up in places such as the neck, stomach, under the arms or in the groin area that may take on a color that has hints of blue or purple. Normally, these kinds of abnormalities form as a result of less serious infections and do not generally persist for longer than a week, or so.
