3. Frequent fever and infection
These may indicate leukemia, a kind of cancer that attacks blood cells and develops in the bone marrow. The marrow produces abnormal white blood cells and affects the body’s ability to fight infections.
4. Difficulty swallowing
It may be a symptom of esophageal or throat cancer. In some cases, it is considered as an early symptom of lung cancer.
5. Swollen lymph nodes or lumps on the neck, underarm or groin
These may be a sign of changes in the lymphatic system, which can oftentimes be a symptom of cancer.
6. Excessive bruising and bleeding that does not stop
These are a sign that there is something wrong with the platelets and red blood cells. In some cases, this can indicate leukemia. After some period, the number of leukemia cells becomes a lot higher than that of red blood cells and platelets, and the blood cannot perform its function to carry oxygen and clot.
7. Weakness and fatigue
General fatigue and weakness may be a sign of many kinds of cancer. Consider any other weird symptom that you have in order to determine whether it is cancer. Consult your doctor every time you feel exhausted for no reason, also in cases when proper sleeping does not help either.
8. Bloating or abdominal weight gain
Unexplained abdominal bloating may sometimes be a sign of ovarian cancer. It occurs suddenly and continues on and off for a long time.
9. Feeling of fullness and being unable to eat
In some cases, women diagnosed with ovarian cancer have no appetite and cannot eat, even when they have not had a decent meal for some time.
