Nasopharyngeal (nay-zoh-fuh-RIN-jee-ul) carcinoma is cancer that occurs in the nasopharynx, which is located behind your nose and above the back of your throat. Nasopharyngeal carcinoma is difficult to detect early. That's probably because the nasopharynx isn't easy to examine and symptoms of nasopharyngeal carcinoma mimic those of other, more-common conditions.
Gastric (stomach) cancer occurs when cancer cells form in the lining of the stomach. Risk factors include smoking, infection with H. pylori bacteria, and certain inherited conditions.
Lymphomas are cancers of the lymphatic system and usually originate in the lymph nodes or the spleen and spread through the lymphatic system.
