Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

What is Cancer?02:12

What is Cancer?

Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of patients who died from...

Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Summary

Cancer incidence is rising in Iran, a nation undergoing epidemiological transition. Common cancers include stomach, esophagus, and breast cancer, with earlier onset in women and increasing colorectal cancer rates.

Area of Science:

  • Oncology
  • Epidemiology
  • Public Health

Background:

  • Iran is experiencing an epidemiological transition, shifting from communicable to non-communicable diseases.
  • Cancer is the third leading cause of death in Iran, with rising mortality rates in recent decades.
  • Understanding cancer incidence patterns is crucial for developing early detection and risk factor investigation strategies.

Purpose of the Study:

  • To provide an overview of common cancer incidence in Iran.
  • To identify epidemiological differences in cancer prevalence within the Iranian population.
  • To inform the development of targeted cancer control programs.

Main Methods:

  • A comprehensive literature search was conducted across PubMed, Scopus, and Google Scholar databases.

  • Studies published between 2000 and 2009 focusing on Iranian cancer epidemiological data were included.
  • Data on age-standard incidence rates and common cancer types were extracted and analyzed.

    • Main Results:

    • The overall age-standard incidence rate was 110.43 per 100,000 for males and 98.23 per 100,000 for females.
    • The most common cancers in males were stomach, esophagus, colon-rectum, bladder, and leukemia (excluding skin cancer).
    • The most common cancers in females were breast, esophagus, stomach, colon-rectum, and cervix uteri.
    • Gastrointestinal cancers exhibit high incidence rates in Iran, a region known for this pattern.
    • Breast cancer occurs approximately a decade earlier in Iranian women compared to Western populations.
    • Colorectal cancer incidence is increasing in younger Iranian populations, approaching Western rates.

    Conclusions:

    • Iran faces a significant burden of cancer, particularly gastrointestinal and breast cancers.
    • Distinct epidemiological patterns, such as earlier onset of breast cancer and rising colorectal cancer rates, require specific public health interventions.
    • Further research into population risk factors and enhanced early detection programs are essential for cancer control in Iran.
