You may have never heard of anal cancer. This disease is not talked about much because cases of the disease are not as common as lung or breast cancer, but you should still be aware of it, writes krasotaizdrave.

According to the Spanish Association for the Fight against Cancer, anal cancer accounts for only 1.9% of all tumor diseases of the digestive system.

Although the percentage is not very high, you should know that in recent years the cases of this disease have increased sharply due to the presence of risk factors such as:

• Smoking
• Longer life expectancy
• Human papillomavirus (HPV) infections

The disease mainly affects men, but it also occurs in women over 50 years of age.

The biggest problem with anal cancer is that it often progresses without any visible symptoms.
