Overview of cancer treatments Review

Review

• Endoscopic resection removes early tumors with

small tools that are guided down the throat and

into the stomach.

• A gastrectomy removes some or all of the stomach

along with nearby lymph nodes through an incision

made in the belly area. This surgery may be done

through one large cut (open method) or a few

small cuts (minimally invasive method).

• Radiation therapy uses high-energy rays to kill

cancer cells or stop new cancer cells from being

made.

• Chemotherapy stops cancer cells from completing

their life cycle so they can’t increase in number.

• One type of targeted therapy stops the growth of

new blood vessels into stomach tumors. Without

blood, cancer cells starve and die. A second type

of targeted therapy for stomach cancer stops the

cancer cells from receiving certain growth signals.

• Clinical trials give people access to new tests

and treatments that otherwise can’t usually be

received. These new tests and treatments may, in

time, be approved by the FDA.
