General fatigue
One of the most common symptoms of malignant mesothelioma cancer includes the feeling of general fatigue and weakness. The general weakness involves the using up of protein and energy from the body by the growing tumors. The consumption of tumors as they grow leaves lesser resources available for the normal cells of the body to function properly, which leads to feelings of fatigue and weakness. Moreover, the cancerous cells from the tumors affect the hormone levels of the body and secrete certain toxins in the body that affects the normal functioning of the healthy cells.
