Breast Cancer

Part I

For this semester, my class is divided into groups and each group is assigned to do a poster to raise health awareness. The topic of my group is breast cancer and I’m in charge of risk factors for breast cancer. I think this is an interesting topic, and a serious issue that we shall pay attention on. Therefore, I decided to share the part I’m doing.

Risk that cannot change
Gender:
Being a woman is the main risk factor for developing breast cancer. This is due to the breast cells of woman are constantly exposed to the growth-promoting effects of the female hormones estrogen and progesterone. Breast cancer can affect men as well. Male breast cancer accounts for approximately 1% of the total cases. So, never assume that man will not develop breast cancer!!!

Age:
The risk of developing breast cancer increases with age. Means older people have higher risk of getting breast cancer.

Personal history of breast cancer:
A woman with cancer in one breast has a 3- to 4- fold increased risk of developing a new cancer in the other breast or in another part of the same breast.

Family history of breast cancer:
Breast cancer risk is higher among women whose close blood relatives have this disease. Having 1 first-degree relative (mother, sister, or daughter) with breast cancer approximately doubles a woman’s risk. Having 2 first-degree relatives increases her risk 5-fold. Although the exact risk is not known, woman with a family history of breast cancer in a father or brother also have an increased risk of breast cancer. About 20% to 30% of women with breast cancer have a family member with this disease.

hmm…I think I don’t want to make this post till too long…although there’s still a lot more to go. I’m just afraid that you’ll lose appetite when you see such a long post. Haha….i’ll continue to post about this, soon. VERY SOON! Hope you’ll aware about breast cancer after reading this.

A few more possible risk factors I can add. Sleeping in total darkness may lower the risk of breast cancer. Blind women have a very low risk of breast cancer, and women that work night shifts have a higher risk. It is felt that melatonin which is manufactured in the brain in darkness may lower estrogen levels. Getting adequate vitamin D is important. A recent study showed that women who consumed (or got through sunshine) 2000 IU's of vitamin D per day had only half the risk of breast cancer. Cleaning house may help as well. Another recent study showed that "domestic exercise" lowered the risk of breast cancer. Great post!
