叫做賁(音讀bēn)門癌(Gastric Cardia Cancer).

Two Types of Stomach (Gastric) Cancer:

• Gastric Cardia Cancer
• Non-Cardia Gastric Cancer

There are two types of gastric cancer: gastric cardia cancer, which occurs in the top portion of the stomach near the junction of the esophagus, and non-cardia gastric cancer, which may be found in all other areas of the stomach. These two types of cancer have different risk factors and patterns of incidence.

While the overall incidence of gastric cancer is decreasing in the US, this reduction in gastric cancer cases applies primarily to non-cardia gastric cancer. This reduction in non-cardia gastric cancer is believed to be due to better diet, better food refrigeration, and use of antibiotics to treat helicobacter pylori bacteria (H. pylori bacteria) infection, a major risk factor for non-cardia gastric cancer. Conversely, cardia gastric cancer, rare at one time, is now increasing in Western nations for reasons for that are still unclear, and it accounts for about 50% of all stomach cancer in men in the US.

Symptoms of Stomach (Gastric) Cancer

Early symptoms of gastric cancer include indigestion and stomach pain or discomfort; a sense of fullness in the upper abdomen especially after eating, loss of appetite, and mild nausea. More advanced stomach cancer may produce unexplained weight loss, stomach pain, vomiting, tarry (black) stool, trouble swallowing, jaundice (yellowing of the skin and eyes), and swelling of the abdomen.

咽喉癌= Throat (Laryngeal and Pharyngeal) Cancer

What are the symptoms of head and neck cancers?

The symptoms of head and neck cancers may include a lump or a sore that does not heal, a sore throat that does not go away, difficulty in swallowing, and a change or hoarseness in the voice. These symptoms may also be caused by other, less serious conditions. It is important to check with a doctor or dentist about any of these symptoms. Symptoms that may affect specific areas of the head and neck include the following:

Oral cavity. A white or red patch on the gums, the tongue, or the lining of the mouth; a swelling of the jaw that causes dentures to fit poorly or become uncomfortable; and unusual bleeding or pain in the mouth.

Pharynx. Trouble breathing or speaking; pain when swallowing; pain in the neck or the throat that does not go away; frequent headaches, pain, or ringing in the ears; or trouble hearing.

Larynx. Pain when swallowing or ear pain.

Paranasal sinuses and nasal cavity. Sinuses that are blocked and do not clear; chronic sinus infections that do not respond to treatment with antibiotics; bleeding through the nose; frequent headaches, swelling or other trouble with the eyes; pain in the upper teeth; or problems with dentures.

Salivary glands. Swelling under the chin or around the jawbone, numbness or paralysis of the muscles in the face, or pain in the face, the chin, or the neck that does not go away.
