Cancer of Unknown Primary Symptoms
Symptoms of cancer of unknown primary (CUP) vary from person to person and depend on where the cancer has spread. They may include:
- Swollen lymph nodes that are firm and not painful
- Mass in the abdomen that can be felt from the outside or causes a feeling of fullness after a small meal
- Shortness of breath
- Pain in the chest or abdomen
- Pain in the bones
- Skin tumors
