Why is it that one cancer (testicular cancer) has a good response to treatment even when it is in an advanced stage and then advanced lung cancer has a very poor response to treatment when it is in an advanced stage?

brandon - You're on your way to becoming a cancer specialist. In addition to the two cancers you mentioned, there are about 200 others that may be found in humans. There is no one cancer of the testis, but the main four are types of cancer that develop in the testes are seminoma, teratoma, embryonal carcinoma, and choriocarcinoma. They vary greatly in their malignant behavior from very curable to deadly and very different in their response to treatment. . There are several other cancers of the testis. Lung cancers are divided into two main groups = non small-cell and small-cell types. Non-small cell lung cancer (NSCLC) NSCLC accounts for about 80% of lung cancers. There are different types of NSCLC, including: Squamous cell carcinoma (also called epidermoid carcinoma). This is the most common type of NSCLC. It forms in the lining of the bronchial tubes and is the most common type of lung cancer in men. Adenocarcinoma. This cancer is found in the glands of the lungs that produce mucus. This is the most common type of lung cancer in women and also among people who have not smoked. Bronchioalveolar carcinoma. This is a rare subset of adenocarcinoma. It forms near the lungs' air sacs. Recent clinical research has shown that this type of cancer responds more effectively to the newer targeted therapies. Large-cell undifferentiated carcinoma. This cancer forms near the surface, or outer edges, of the lungs. It can grow rapidly. Small cell lung cancer (SCLC) SCLC accounts for about 20% of all lung cancers. Although the cells are small, they multiply quickly and form large tumors that can spread throughout the body. Smoking is almost always the cause of SCLC. Responses to treatment and aggressiveness vary. There is no simple and short answer to your original question.
