Lymphoma is also called MALT lymphoma or mucosa-associated lymphoid tissue lymphoma. They are solid tumors and are the second most common type of stomach cancer.
Leiomyosarcoma
Leiomyosarcoma is cancer that begins in the smooth muscle cells in the walls of the stomach. This cancer grows uncontrollably and forms tumors.
