Kanker lambung, atau yang sering disebut kanker gaster, terjadi ketika sel-sel abnormal tumbuh secara tidak terkendali di lapisan dinding lambung. Lama-kelamaan, sel-sel ini bisa membentuk tumor dan berpotensi menyebar ke organ sekitarnya atau bagian tubuh lainnya jika tidak segera ditangani.
Sebagian besar kanker lambung bermula dari lapisan terdalam lambung, lalu perlahan-lahan menembus lebih dalam ke dinding lambung. Karena itu, deteksi dini memegang peranan penting dalam meningkatkan keberhasilan pengobatan.
Seberapa Umum Kanker Lambung?
Kanker lambung termasuk salah satu jenis kanker saluran pencernaan yang cukup sering ditemui di seluruh dunia. Berdasarkan data statistik kanker global, penyakit ini masih menjadi masalah kesehatan yang serius, terutama di wilayah Asia. Di Malaysia sendiri, kanker lambung masuk dalam daftar kanker yang paling banyak terdiagnosis setiap tahunnya.
Meski bisa menyerang orang dewasa di usia berapa pun, kanker ini lebih sering ditemukan pada mereka yang berusia di atas 55 tahun, dan kasusnya lebih banyak terjadi pada pria dibandingkan wanita.
Gejala Umum Kanker Lambung
Kanker lambung stadium awal seringkali tidak menunjukkan gejala yang jelas. Seiring perkembangan penyakit, penderita mungkin akan merasakan:
- Gangguan pencernaan atau rasa panas di dada yang terus-menerus
- Perut terasa penuh meski baru makan sedikit
- Nafsu makan berkurang
- Berat badan turun tanpa sebab yang jelas
- Mual atau muntah
- Rasa tidak nyaman atau nyeri di perut
- Susah menelan
- Muntah darah atau ada darah di tinja
- Kelelahan atau kelemahan
Because these symptoms can resemble common digestive problems, many patients are diagnosed at a later stage.
Faktor Risiko
Several factors may increase the risk of developing stomach cancer, including:
- Merokok
- Obesitas atau kelebihan berat badan
- Chronic stomach infections such as Helicobacter pylori (H. pylori)
- Family history of stomach cancer
- Pola makan yang kurang sehat
- Long-term stomach inflammation
- Genetic mutations or inherited syndromes
- Usia yang lebih tua
People with a family history of stomach cancer may have a higher risk and should consider regular medical check-ups.
Types of Stomach Cancer
There are several types of stomach cancer, including:
- Adenokarsinoma. The most common type, accounting for the majority of stomach cancer cases. It starts in the glandular cells of the stomach lining.
- Gastrointestinal Stromal Tumor (GIST). A rare type that develops in specialized cells within the stomach wall.
- Limfoma. Cancer that begins in the immune system cells located in the stomach.
- Neuroendocrine or Carcinoid Tumors. Tumors that arise from hormone-producing cells in the stomach.
Stages of Stomach Cancer
Doctors classify stomach cancer into stages to determine how far the disease has spread.
- Stadium 0–I: Cancer is limited to the inner layers of the stomach.
- Stage II–III: Cancer has spread deeper into the stomach wall or nearby lymph nodes.
- Stadium IV Cancer has spread to distant organs such as the liver, lungs, or bones.
Understanding the stage helps doctors create a personalized treatment plan.
How Is Stomach Cancer Diagnosed
Doctors may recommend several tests to confirm stomach cancer and determine its stage, including:
- Endoscopy
- Biopsi
- CT scan
- MRI scan
- PET scan
- Tes darah
- Ultrasonografi (USG)
- X-ray examinations
A biopsy is usually necessary to confirm whether cancer cells are present.
Treatment Options for Stomach Cancer
Treatment depends on the stage of the cancer, the patient’s overall health, and treatment goals. Common treatment methods include:
- Operasi
- Kemoterapi
- Radioterapi
- Terapi bertarget
- Imunoterapi
- Minimally invasive treatments

Minimally invasive treatments are increasingly used in cancer care because they aim to target cancer cells while reducing damage to healthy tissues.
Some advanced minimally invasive technologies include:
- Terapi intervensi
- Ablasi gelombang mikro
- Krioterapi
- Nanoknife therapy
- Particle implantation therapy
- Targeted therapies
Potential benefits may include:
- Smaller wounds and less pain
