Stomach Cancer (Gastric Cancer)

Personalised treatments designed to fight cancer while minimising side effects.

What is Stomach (Gastric) Cancer?

Stomach cancer, also known as gastric cancer, begins when malignant (cancerous) cells form in the inner lining of the stomach. Over time, these cells can grow into a tumour and spread deeper into the stomach wall and to nearby organs. Most stomach cancers develop from the glandular cells of the stomach lining, and are called adenocarcinomas.

How common is stomach cancer in the Philippines?

Stomach cancer (gastric cancer) is less common than the Philippines’ top cancers (such as breast, lung, colorectal, and liver cancer), but it still contributes to a meaningful number of cancer deaths nationwide. 

According to the IARC Global Cancer Observatory (GLOBOCAN 2022): 

  • The Philippines had an estimated 4,155 new stomach cancer cases in 2022, ranking 12th among all cancers (about 2.2% of all new cancer cases). 
  • There were an estimated 3,434 deaths from stomach cancer in 2022, ranking 10th among cancer deaths (about 3.0% of all cancer deaths). 
  • The estimated age-standardized incidence rate (ASR) is 4.2 per 100,000, and the age-standardized mortality rate is 3.5 per 100,000.  

Because early symptoms can be non-specific, timely medical evaluation is important if symptoms persist or worsen. 

What Are the Signs and Symptoms of Stomach Cancer?

Early stages of stomach cancer may not cause clear symptoms, which makes detection difficult. As the disease progresses, patients may experience:

If these symptoms persist, medical evaluation is important.

Screening and Early Detection

Unlike breast or colorectal cancer, there is currently no national screening programme for stomach cancer in Philippines. However, early detection is possible through gastroscopy (endoscopy), particularly for people at higher risk, such as those with:

  • A family history of gastric cancer
  • Chronic H. pylori infection
  • Stomach polyps or chronic gastritis
  • Diets high in smoked, salted, or pickled foods

For high-risk individuals, regular monitoring and early medical consultation are recommended. Detecting stomach cancer early offers the best chance for successful treatment.

How is Stomach Cancer Diagnosed?

Diagnosis usually involves a combination of:
Gastroscopy (endoscopy)

A thin tube with a camera is inserted through the mouth to view the stomach lining and take biopsies

Tissue samples are examined under a microscope to confirm cancer

CT scans, PET scans, and ultrasounds help assess the extent of the disease

To check overall health and detect tumour markers

Early diagnosis can improve treatment outcomes.

What Are the Causes and Risk Factors?

Several factors increase the risk of developing stomach cancer:

  • Helicobacter pylori (H. pylori) infection – a common bacterial infection linked to stomach ulcers and cancer
  • Dietary factors – high intake of salted, smoked, or pickled foods
  • Smoking and alcohol consumption
  • Family history of gastric cancer
  • Chronic gastritis or stomach polyps
  • Older age and male gender

What Are the Types of Stomach Cancer?

The main type is adenocarcinoma, which makes up more than 90% of cases. Other rarer types include:

Lymphoma of the stomach

Cancer of the immune system cells in the stomach wall

Cancers of the connective tissue

Slow-growing cancers arising from hormone-producing cells

What Are The Stages of Stomach Cancer?

Staging describes how far the cancer has spread:

Stage I

Cancer is limited to the stomach lining or wall

Cancer has grown deeper into the stomach wall and may involve nearby lymph nodes

Cancer has spread to distant organs (such as the liver, lungs, or bones)

What are Stomach Cancer Treatments?

Treatment depends on the stage, type, and overall health of the patient. At OncoCare Philippines, options include:

Surgery

Removal of part or all of the stomach (gastrectomy) for curative intent.

Radiotherapy

High-energy rays to kill cancer cells, sometimes combined with chemotherapy.

Targeted Therapy

Newer treatments that attack cancer cells more precisely, or boost the body’s immune system to fight cancer.

Immunotherapy

Newer treatments that attack cancer cells more precisely, or boost the body’s immune system to fight cancer.
Every patient’s treatment plan is carefully tailored to their needs, with the goal of achieving the best possible outcomes while preserving quality of life.

Skin Cancer

Personalised treatments designed to fight cancer while minimising side effects.

What is Skin Cancer?

Skin cancer develops when abnormal skin cells grow uncontrollably, often due to damage from ultraviolet (UV) radiation from the sun or tanning beds. It is one of the most common cancers worldwide and includes different types such as basal cell carcinoma, squamous cell carcinoma, and melanoma. While some forms are less aggressive, others like melanoma can spread quickly if not detected and treated early.

How common is Skin Cancer in the Philippines?

Skin cancer is less common in the Philippines than in many Western countries, but it still occurs and can be serious—especially when detected late. Based on IARC Global Cancer Observatory (GLOBOCAN) (GLOBOCAN 2022) estimates, the Philippines had about 508 new cases of melanoma (skin cancer) and around 299 deaths in 2022.  

However, non-melanoma skin cancers (such as basal cell carcinoma and squamous cell carcinoma) are often under-counted in national estimates and may not be fully captured in standard cancer statistics. Local reports help show the broader picture: the Philippine Dermatological Society documented 2,102 basal cell carcinoma cases and 614 squamous cell carcinoma cases from 2011–2021, noting likely underestimation without a complete national registry view. The Department of Health (Philippines) also cited over 2,700 Filipinos diagnosed with skin cancer from 2011–2021. 

Early detection and prevention (sun protection and checking new or changing skin lesions) remain key—particularly for people with high sun exposure. 

What Are the Signs and Symptoms of Skin Cancer?

Skin cancer can present in many ways, but common warning signs include:

Any persistent lump or swelling should be checked by a doctor, especially if it is growing.

How is Skin Cancer Diagnosed?

Diagnosis usually involves:

  • Clinical examination of the skin by a dermatologist or oncologist
  • Dermatoscopy for detailed visual inspection
  • Skin biopsy to confirm the type of cancer
  • Imaging tests (CT, MRI, or PET scans) if there is suspicion of spread

What Causes Skin Cancer and Who is at Risk?

The main cause of skin cancer is prolonged exposure to UV radiation, either from the sun or tanning devices. Risk factors include:

The good news is that many skin cancers are preventable. Protecting your skin with sunscreen, wearing protective clothing, avoiding peak sun hours, and performing regular skin checks can reduce risk and help detect changes early.

What Are the Types of Skin Cancer?

Basal Cell Carcinoma (BCC

The most common but usually slow-growing and less likely to spread

Can grow deeper and spread if untreated

The most dangerous form, arising from pigment-producing cells (melanocytes), with high potential to spread to other organs

Merkel cell carcinoma, Kaposi sarcoma, and others

What Are the Stages of Skin Cancer?

Skin cancer staging depends on tumour size, depth of invasion, lymph node involvement, and spread to other organs.

Early stage (Stage 0–I)

Localised, often curable with surgery

May involve deeper skin layers or nearby lymph nodes

Cancer has spread (metastasised) to distant organs

What Are the Treatments for Skin Cancer?

Treatment depends on the type, size, and stage of cancer:

Surgery

Wide local excision, Mohs micrographic surgery for precise removal while sparing healthy tissue.

Radiotherapy

For cancers not suitable for surgery or to control spread.

Targeted Therapy

Especially effective in advanced melanoma.

Immunotherapy

Especially effective in advanced melanoma.

Photodynamic therapy & topical treatments

For superficial skin cancers.

At OncoCare Philippines, treatment decisions are personalised, taking into account medical evidence, cosmetic outcomes, and patient needs.
