What is the first treatment for stomach cancer?

Short answer
The first treatment tried for stomach cancer is often chemotherapy, either before surgery or as part of treatment for cancer that cannot be removed.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

How the first plan is chosen
Stomach cancer treatment starts with staging and testing the tumour. These results show whether an operation may remove the disease and whether markers such as HER2 could make targeted treatment relevant. Chemotherapy before surgery can shrink or control the tumour and help the team plan the next step. If an operation is suitable, stomach removal surgery may follow, with the extent guided by the tumour's position. Immunotherapy can be added or considered for selected disease according to tumour features and the wider treatment plan.
Preparing for treatment
Bring your biopsy, scan and blood-test information to the oncology appointment. Discuss nutrition early because stomach symptoms and treatment can affect eating, weight and hydration. Ask whether the plan includes chemotherapy before surgery, how HER2 testing changes options, and which symptoms should be reported between visits. Keep a written list of medicines and any swallowing, vomiting or pain changes.
When to seek care
Get urgent medical help for vomiting that prevents fluids, black or bloody stools, severe abdominal pain, fainting, confusion or signs of dehydration. During treatment, promptly report fever, repeated vomiting, new bleeding or inability to eat and drink, because these may need same-day advice.
Questions for your doctor
What does staging show about surgery? Is chemotherapy planned before an operation? Has the tumour been tested for HER2 and other treatment markers? How can I maintain nutrition during the first treatment?
Questions people ask
Will I need stomach removal surgery?
Some people do, while others have a different plan based on tumour location, spread, health and response to initial treatment.
What is HER2-targeted therapy?
It is a treatment considered when testing shows HER2 on the cancer cells and the oncology team believes it fits the plan.
