Symptoms of mesothelioma may not appear until 30 to 50 years after exposure to asbestos. Once the symptoms begin to appear, they include:

- Coughing
- Shortness of breath or difficulty breathing
- Difficulty sleeping
- Night sweats
- Weight loss
- Pain in chest and abdomen
- Fluid in the chest

Mesothelioma stages:

Stage I: Mesothelioma is present on one side of the chest only and isn’t growing into the chest wall.

Stage II: Mesothelioma invades the chest wall or involves the esophagus (food passage connecting the throat to the stomach), heart, or has grown into the pleura on the other side of the chest.. The lymph nodes in the chest may also be involved.

Stage III: Mesothelioma has grown through the diaphragm into the peritoneum (lining of the abdominal cavity) or has spread to lymph nodes beyond those in the chest.

Stage IV: Mesothelioma has spread through the bloodstream to other organs (metastases).
