Hemorrhoids or colorectal cancer? How to make the difference?

How to tell the difference between hemorrhoids and cancer.

Hemorrhoids are swollen veins inside the rectum and anus. They may become irritated and bleed, hurt or itch. Cancer develops because cells grow out of control. Anal cancer can cause a growth or lump in the rectum or anus, while colon cancer affects the colon and does not cause lumps or bumps that a person can feel with their hand. It is not always possible to tell the difference between cancer and hemorrhoids.

Symptoms are more likely to be due to hemorrhoids if:

– the person has risk factors for hemorrhoids, such as current pregnancy, constipation, history of straining to have a bowel movement or history of hemorrhoids

– symptoms improve with home treatment, higher fiber diet, sitz baths or application of hemorrhoid creams

– the person may feel a swollen bump or lump near the anus or see a swollen vein using a mirror

– symptoms come and go but do not get progressively worse or cause other symptoms, such as weight loss

It is important to speak with a doctor about any changes in the state of health, because it is much easier to treat cancer at its early stages.

– being aged over 55 years

Causes of hemorrhoids

All everyone can have hemorrhoids, and the risk tends to increase with age.

Internal hemorrhoids tend to be painless, while external hemorrhoids can be painful.

A hemorrhoid occurs when a vein in the rectum becomes irritated and inflamed. It gets bigger, causing the stool to rub against it. It can be painful.

Hemorrhoids are natural. Here are some risk factors:

– pregnancy, overweight or obesity, as they put increased pressure on the rectum

– have constipation or follow a low fiber diet

– strain to have a bowel movement

– having a sedentary lifestyle

The causes of cancer

The Cancer is a complex disease that has no single cause. Certain risk factors increase the likelihood of developing anal cancer, including

– having a history of human papillomavirus

– smoking

– suffering from chronic injuries to the anus

– being older 55 years

A person is more likely to develop colon cancer if she

– are overweight or obese

– have a family history of colon cancer

– eat a lot of fried foods

– smoke

– consume a lot of alcohol

Genetics can also play a role. People with a family history of cancer may be more likely to develop this disease. Age also increases the risk of cancer, and most cancers are uncommon in young people.

Diagnosis of hemorrhoids and cancer

A doctor can usually diagnose hemorrhoids by doing a simple rectal exam and taking a medical history. If he finds an unusual growth that is not a hemorrhoid, he may recommend a biopsy to screen for anal cancer.

It is more difficult to diagnose colon cancer. Indeed, cancer markers do not necessarily correlate with the presence or absence of cancer. Therefore, the doctor may also recommend a test depending on the symptoms. For example, he may ask if a person has bleeding but no hemorrhoids or if treatment for hemorrhoids does not relieve their symptoms. He may perform blood tests to look for cancer markers or recommend a colonoscopy to look for growths. A colonoscopy involves inserting a thin, flexible tube into the rectum while the person is asleep or sedated. If the doctor finds a growth, he may examine it in the laboratory or recommend a biopsy.
