Borstkanker

Breast cancer is the most common form of cancer among Dutch women. Breast cancer is a rare disease before the thirtieth year. After that age, the number of women that breast cancer gets gradually increases. About 75% of people in whom breast cancer is detected, is 50 years of age or older. Breast cancer most frequently occurs in women between 50 and 75 years.

About 5 to 10% of all women with breast cancer has gotten the disease by a hereditary predisposition. The cause is often a change in the genetic material of the BRCA1 gene or the BRCA2 gene (BRCA stands for BReast CAncer). The inherited form is usually set at a younger age-between 35 and 60 years. Patients with the inherited form are at increased risk of getting cancer in both breasts (in the place of to one chest) and also an increased risk of ovarian cancer.

Women who carry the BRCA 1 or 2 breast cancer gene have 55 to 85% chance to for their 80th to get breast cancer. The risk of ovarian cancer is 40-60% (BRCA1) and 15-20% (at BCRA2).
The risk of breast cancer for women without hereditary predisposition is around 11%.
The risk of ovarian cancer for women without hereditary predisposition is 1%.

Men can also get breast cancer. They have 0.1% chance. In men with a mutation in BRCA1 it is estimated on a few percentage points and with a BRCA2 mutation at 7%. 0.2% of all cancers in men is breast cancer.

Most known risk factors of breast cancer are:

• little or no children.
• get the first child later in life.
• for the first time at a young age menstruate.
• come late in the transition.
• very dense glandular tissue in the breast have.

• short or no breast-feeding.
• swallowing the pill (this risk decreases when you stop taking the pill).
• drink more than one glass of alcohol every day over a longer period of time.
• little exercise.
• overweight during and after the transition.

Scientific studies on the relationship between diet and breast cancer:
The review articles of randomized, placebo-controlled double-blind human studies (Rcts) answer the following question:
"Is swallowing food supplements make sense?". Yes at a positive conclusion and no in the case of a negative conclusion.

The review articles of cohort studies or case-control studies answer the following question:
"Should I change my diet?".
