The early signs of gastric cancer may include nausea, vomiting, or mild acid reflux, which are symptoms similar to those of gastritis, stomach ulcers, or duodenal ulcers. Therefore, initially, these patients may not take their condition seriously, assuming they might just have gastritis or peptic ulcers. These are some of the early manifestations of gastric cancer, and some patients may also experience discomfort and a feeling of fullness after eating.

Mid-stage symptoms of gastric cancer

Symptoms of mid-stage gastric cancer can include nausea, vomiting, poor appetite, decreased food intake, and upper abdominal pain, as well as symptoms related to the digestive tract. Some patients may also experience black stool or even vomiting blood, which are symptoms of upper gastrointestinal bleeding. Additionally, there can be bloating and abdominal pain. If the tumor is located near the pylorus and causes pyloric obstruction, clinical symptoms will include vomiting, vomiting of overnight food, and resulting in gastric retention. This can lead to significant symptoms such as abdominal pain, bloating, acid reflux, and nausea.

What can stomach cancer patients eat?

Gastric cancer refers to a malignant tumor that occurs in the gastric mucosal epithelium. Special attention should be paid to the diet, appropriately supplementing with multivitamins and consuming more fresh foods, such as fresh green vegetables and fruits. The diet should be diverse to avoid favoring certain foods overly and to ensure the intake of a variety of nutrients. It is also necessary to eat some meat for protein, avoid moldy foods, reduce the consumption of pickled, salted, smoked foods, and those rich in nitrites, and avoid the irritation from strong tea, coffee, and hard liquor. In addition to dietary measures, active treatment for early-stage gastric cancer can include endoscopic mucosal resection, or one may opt for a major gastric resection surgery or radiotherapy, while maintaining a good psychological state and sufficient sleep.

How is gastric cancer treated?

The treatment methods for gastric cancer include surgery, chemotherapy, and radiotherapy, as well as broad-spectrum targeted therapies against angiogenesis, such as apatinib. Immunotherapy is also an option. However, the specific treatment plan is based on a comprehensive consideration of various factors, including the stage of the cancer and the general condition of the patient. The principle is that for early-stage gastric cancer patients, if the surgeon assesses that surgery is feasible, then radical surgical treatment is primarily used. For advanced-stage patients who are in generally good condition, chemotherapy is the main treatment, combined with a consideration of whether to undergo radiotherapy. For those in very advanced stages, who may not be in good health or those who have had chemotherapy with poor results, anti-angiogenic drugs like apatinib can be chosen as a subsequent treatment.

Is chemotherapy for gastric cancer torturous?

The first common side effect of chemotherapy drugs is gastrointestinal reactions, such as nausea, vomiting, decreased appetite, diarrhea, constipation, or bloating, and other such gastrointestinal symptoms. The second is bone marrow suppression, such as decreases in white blood cells and platelets; a decrease in white blood cells can easily lead to infections, and low platelets can lead to a tendency to bleed. There are also liver and kidney damage, numbness of hands and feet in the peripheral nervous system, and clinical symptoms such as fingernail darkening, pigmentation, or hand-foot syndrome caused by fluorouracil. The severity of chemotherapy side effects varies greatly among patients and is related to each patient's general condition, exhibiting significant individual differences. Some patients may experience severe reactions to chemotherapy, while others may have milder reactions. However, during chemotherapy, we provide corresponding symptomatic treatments such as gastric protection, antiemetics, and cardioprotection, among others, to try to minimize the side effects caused by chemotherapy.

Is gastric cancer contagious?

Gastric cancer is a malignant tumor occurring in the epithelial cells of the gastric mucosa. It is non-contagious. Currently, the incidence of gastric cancer is relatively high, primarily due to Helicobacter pylori infection, adverse environmental factors, and dietary irritants. Genetic factors also play a significant role, with 10% of gastric cancer patients having a family history. Those with a family history of gastric cancer have an incidence rate that is 2 to 3 times higher than the general population. Additionally, precancerous lesions can also induce gastric cancer, such as intestinal metaplasia, gastric polyps, residual gastritis, and gastric ulcers. Typical symptoms include indigestion, anemia, lack of appetite, aversion to food, and fatigue. Currently, gastroscopy combined with mucosal biopsy is the most reliable diagnostic method.
