What is cancer?
Cancer is a group of diseases characterized by the uncontrolled growth of cells in the body. Normally, cells grow, divide, and die at the appropriate time. But in cancer, this process goes awry, and cells multiply abnormally and sometimes spread to other parts of the body (metastasis).
What is the difference between a healthy cell and a cancer cell?
Healthy cell: regular life cycle, limited growth, natural death (apoptosis)
Cancer cell: unlimited growth, resistance to death, invasion of other tissues
What causes cancer?
Cancer often occurs due to a combination of genetic, environmental, and lifestyle factors. Some common factors include:
1. Genetic factors
2. Lifestyle
3. Environment
4. Viral and microbial factors
General Cancer Symptoms
Cancer symptoms vary depending on the type, but some general warning signs that should not be ignored include:
Unexplained weight loss
Extreme and persistent fatigue
A lump or bump on the body
Changes in skin or moles
Unusual bleeding or discharge
A cough or hoarseness that does not improve
Persistent digestive or urinary problems
👈 Note: The presence of these symptoms does not always mean cancer, but it does require immediate medical attention.
Common Types of Cancer
Cancers are classified based on where they start. Here are some of the more common types:
1. Breast cancer:
The most common cancer in women. It usually appears as a lump in the breast.
2. Colon cancer:
One of the leading causes of cancer-related deaths, especially in adults over 50.
3. Leukemia:
Starts in the bone marrow and blood and disrupts the production of blood cells.
4. Prostate cancer:
The most common type in middle-aged and elderly men. It is often characterized by difficulty urinating.
5. Stomach cancer:
It usually has no specific symptoms in the early stages and is therefore diagnosed late.
6. Childhood cancer:
Includes leukemia, brain tumors, neuroblastoma. Early diagnosis is vital.
Ways to diagnose cancer
Early detection significantly increases the chances of successful treatment. Common diagnostic methods include:
Blood tests and tumor markers
Mammography (for the breast)
Colonoscopy (for the colon)
MRI and CT Scan
Biopsy (taking a sample of suspicious tissue)
🔍 Important: Regular examination and screening are very important for high-risk individuals.
Cancer Treatment Methods
Treatment methods vary depending on the type, stage of progression, and patient condition. Some common methods include:
1. Chemotherapy:
Using strong drugs to kill cancer cells.
2. Radiotherapy:
Using radiation to destroy cancer cells.
3. Surgery:
To remove a lump or tumor at certain stages.
4. Immunotherapy:
Boosting the body’s immune system to fight cancer cells.
5. Targeted therapies:
Targeting specific molecules or genes in a cancer cell.

Rare Cancers: When Danger Comes from an Unexpected Place
Rare cancers are those that affect fewer than 6 per 100,000 people per year. Although they are less common, they are often more difficult to diagnose and more complex to treat.
The most important rare cancers are:
Sarcomas: These include cancers of soft tissue such as muscle, fat, blood vessels, and bone. A common type of these is Ewing’s sarcoma, which is seen in teenagers.
Neuroendocrine tumors: These arise from hormone-producing cells in various parts of the body.
Merkel cell carcinoma: A rare but aggressive type of skin cancer.
Rare lymphomas: Such as T-cell lymphoma.
Retinoblastoma: Very rare and hereditary in children.
Cancer of the retina (retinoblastoma): Rare but potentially dangerous.
Characteristics:
General and vague symptoms (e.g. pain, swelling, general weakness)
Need specialized genetic or pathology testing for diagnosis
Lack of public awareness of symptoms leads to late diagnosis
Why should we be aware of rare cancers?
Greater awareness of these cancers could lead to earlier diagnosis, better treatment, and lower mortality rates. They also have less research and funding, and require more attention from charities, researchers, and the community.
Cancer Statistics and Information in Iran
According to the report of the Ministry of Health and the Iranian Cancer Research Center:
General Statistics:
About 130,000 new cases of cancer are registered in Iran annually.
Breast cancer in women, abdominal cancers in men under 40, and leukemia in men over 40 are the most common.
After heart disease, cancer is the second leading cause of death in the country.
Age of onset:
The average age of cancer onset in Iran is 10 years lower than the global average.
The growth of cancer in the young population is particularly worrying.
Reasons for the increase in cancer cases in Iran:
Unhealthy diet (high consumption of fast food and fat)
Air pollution and agricultural toxins
Aging population
Sedentary lifestyle and obesity
These statistics double the importance of awareness, prevention and screening. The Hamdali Foundation strives to play an effective role in reducing the suffering of patients through education, public assistance and support services.
