Gastroesophageal junction carcinoma – This is a type of cancer that develops at the area where the esophagus meets the stomach. It begins when abnormal cells grow uncontrollably in the tissues of this junction. As the disease progresses, these cells may invade deeper layers of the organ walls. The abnormal growth can eventually spread to nearby structures or other parts of the body.
Non-small cell lung cancer – This is a common form of lung cancer that includes several different subtypes. It starts when cells in the lungs undergo genetic changes that cause them to multiply rapidly. The disease can involve the lining of the airways or the lung tissue itself. Over time, the cancerous cells may expand and spread beyond the initial site in the lungs.
Gastric cancer – This disease involves the uncontrolled growth of abnormal cells within the stomach lining. It typically starts in the mucosal layer of the stomach. As the condition advances, the tumor can grow into the deeper layers of the stomach wall. It may also move to other organs through the bloodstream or lymphatic system.
Cervical cancer – This type of cancer originates in the cells of the cervix, which is the lower part of the uterus. It often begins with changes in the cells that line the cervical canal. These abnormal cells can gradually transform into cancerous cells over time. The disease can then spread to the vaginal walls or other pelvic organs.
Ovarian cancer – This cancer develops from cells within the ovaries, which are the female reproductive organs. It starts when cells in the ovaries begin to divide abnormally. The disease can progress by forming masses within the ovaries or on their surfaces. It may eventually involve the fluid-filled spaces in the abdomen.
Endometrial cancer – This is a cancer that begins in the endometrium, which is the inner lining of the uterus. It occurs when cells in this lining grow in an uncontrolled manner. As the disease moves forward, the cancerous layer can thicken and invade the muscular wall of the uterus. It may also spread to nearby pelvic tissues.
Malignant ovarian germ cell tumor – This is a specific type of cancer that arises from the germ cells in the ovaries. These cells are responsible for producing eggs. The disease progresses as these specialized cells transform into cancerous growths. These tumors can grow within the ovary and may eventually affect surrounding pelvic areas.
Malignant testicular germ cell tumor – This cancer develops from germ cells located within the testes. These cells are essential for sperm production. The disease progresses when these cells undergo abnormal transformations and begin to multiply rapidly. The resulting tumors can grow within the testicles and potentially move to other parts of the body.
Malignant extragonadal germ cell tumor – This refers to germ cell tumors that arise in parts of the body outside of the gonads, such as the abdomen or chest. It occurs when germ cells that should have migrated to the reproductive organs instead develop in other locations. The disease involves the growth of abnormal cells in these non-reproductive sites. As it progresses, the tumors can expand and impact nearby organs.
