Stage 3 Stomach Cancer Symptoms: Key Warning Signs
When people start to feel sick all the time, exhausted, or have weird changes in their appetite, they commonly blame stress, acidity, or a hectic schedule. But these indicators can sometimes mean that something is wrong. A lot of people don't know that stomach cancer doesn't usually show signs until it becomes worse. This is why it's so crucial to know the signs of 3 stomach cancer symptoms.
At this point, the cancer has already spread to lymph nodes close by and deeper layers of the stomach. This makes the symptoms worse and easier to see.
Knowing what these indicators signify will help you respond at the correct time and give you a higher chance of getting healthy. This article will talk about the most important warning indicators you should never ignore and why paying attention to them early can make a big impact.
What Stage 3 Stomach Cancer Means
Stage 3 stomach cancer signifies that the tumour has grown beyond the stomach's inner lining. It might have also gotten to the surrounding lymph nodes, which are tiny glands that help keep the body safe. The cancer is still advanced, even though it hasn't spread to distant organs like the lungs or liver yet.
Even if this stage is bad, treatment is still feasible. A lot of patients do well with surgery, chemotherapy, targeted therapy, or a mix of these. You can obtain medical care sooner and have a better chance of surviving if you know the signs of stage 3 stomach cancer early.
Why Symptoms Get Worse in Stage 3
In stages 1 or 2, the tumour is tiny and may not produce many symptoms. But in stage 3, the tumour gets bigger and starts to harm the organs and digestive system that are next to it. This is why the indications of danger became stronger and easier to see.
Knowing these signs can help you figure out when to see a doctor and be tested.
Stomach pain that won't go away
One of the most prevalent indicators of stage 3 stomach cancer is stomach pain that won't go away. This pain could feel like cramps, be dull, or be tight. It frequently grows worse after eating since the development makes it tougher to digest.
Many individuals believe that this pain is caused by acidity or indigestion, but you should never overlook gut pain that doesn't go away. The growth is growing deeper into the walls of the stomach, which makes the pain worse.
Feeling Full Even After Eating a Little. Feeling full early on is also a significant red flag. They say they can't eat a lot since they feel full after a few bites. One cause for this is that the growth could be obstructing part of the stomach or making it smaller.
People typically notice this change when a loved one stops eating well, which is a common indicator of stage 3 stomach cancer.
Severe Heartburn and Indigestion
Indigestion can happen to anyone, but continuous indigestion that keeps getting worse is a serious signal. Symptoms like heartburn, bloating, burping, or discomfort after meals can all point to advanced stomach problems.
These symptoms do not improve with regular medicines, which is an early sign that something serious may be happening inside the stomach.
Unexplained Weight Loss
One of the clearest stage 3 stomach cancer symptoms is sudden weight loss. Even if a person eats normally, the body loses weight because it is working hard to fight the disease. Appetite also decreases, which causes more weight loss.
Any weight loss that happens without trying should always be taken seriously.
Constant Nausea and Vomiting
Many people with stage 3 stomach cancer often feel sick. Nausea may happen after eating or even on an empty stomach. Some patients vomit frequently, and in more serious cases, the vomit may contain blood or look like coffee grounds. This happens because the tumour affects how the stomach moves and digests food.
Blood in Vomit or Stool
Bleeding is a serious warning sign. Sometimes the blood is not visible, but the stool may become black or tar-like. Seeing blood in vomit or stool is another strong indicator of advanced cancer.
These signs need immediate medical attention because they can lead to weakness or anaemia.
Weakness, Tiredness, and Low Energy
Constant tiredness is one of the most common stage 3 stomach cancer symptoms. The body becomes weak when it doesn’t get enough nutrients. Internal bleeding can also cause anaemia, which leads to dizziness, pale skin, and low energy. Even after resting, patients may still feel extremely tired.
Loss of Appetite and No Interest in Food
People with stage 3 stomach cancer often lose their interest in eating. Foods they once enjoyed may no longer seem appealing. Sometimes even the smell of food can cause nausea. This loss of appetite leads to more weakness, making it harder for the body to fight the disease.
Trouble Swallowing in Some Cases
If the tumour is located near the top of the stomach, swallowing may become difficult. Food may feel stuck in the throat or upper chest.
Not everyone has this symptom, but it can be one of the stage 3 stomach cancer symptoms, depending on where the tumour is.
Swelling in the Abdomen
Some people experience swelling in the stomach area. This happens when fluid builds up because the cancer has spread near the stomach lining or lymph nodes. This swelling can make the stomach look bigger or feel uncomfortable.
How Doctors Confirm Stage 3 Stomach Cancer
If these symptoms suggest stomach cancer, doctors perform tests such as endoscopy, biopsy, CT scans, and ultrasound. These tests show how deep the tumour has grown and whether lymph nodes are involved. Early testing improves treatment results and helps the patient get proper care.
How Stage 3 Stomach Cancer Is Treated
Even though stage 3 is serious, many patients still respond well to treatment. Surgery, chemotherapy, and targeted therapy are the most common treatments.
Surgery removes the tumour and nearby lymph nodes. Chemotherapy shrinks the tumour and kills leftover cancer cells. Targeted therapy is used for tumours with certain markers. When treatment starts on time, many people live longer and feel better.
What to Expect While You Recover
It takes time to get better, but most patients start to feel better slowly. Eating smaller meals, drinking enough water, and taking medicines on time all help the body recuperate.
Doctors can make sure that the cancer hasn't come back and that the patient is getting better by seeing them regularly.
Why It's Important to Pay Attention Early
A lot of people don't pay attention to early signs since they think they are just stomach issues. But you should always see a doctor if your symptoms linger for weeks or get worse.
Families can take action early if they know the signs of stage 3 stomach cancer, which can save lives.
