Some types of breast cancer are affected by hormones, like estrogen and progesterone. The breast cancer cells have receptors (proteins) that attach to estrogen and progesterone, which helps them grow. Treatments that stop these hormones from attaching to these receptors are called hormone or endocrine therapy.
What cancers affect hormones?
Types of Hormone-Sensitive Cancer
- Breast cancer. Some types need estrogen and progesterone to grow.
- Ovarian cancer. It can be affected by estrogen.
- Uterine or endometrial cancer. Estrogen and progesterone can fuel some types.
- Prostate cancer. Testosterone and similar hormones can help it grow and spread.
What body systems are affected by breast cancer?
Breast cancer that spreads out of the breast may spread to lymph nodes in the armpit nearest the breast affected by cancer (axillary lymph nodes). It can also spread to other parts of the body, such as the bones, lungs and liver.
What hormone plays a role in breast cancer?
Estrogen stimulates the growth of breast cancers that are estrogen receptor-positive.
What is the relationship between hormones and cancer?
An earlier period and later menopause expose the body to estrogen for longer periods of time for example, increasing cancer risk. Hormone therapy that includes estrogen and progesterone can also potentially increase a woman’s breast cancer risk.
Are all breast cancers hormonal?
After a breast cancer is removed, the cells are tested to see if they have receptors for two hormones: estrogen and progesterone. If a breast cancer is hormone-receptor-positive, it means that it has these hormone receptors, which act like ears or antennae.
What cancers are affected by estrogen?
Estrogen-dependent cancers include breast cancer and colorectal cancer.
What is the deadliest form of breast cancer?
Metastatic Breast Cancer
The most serious and dangerous breast cancers – wherever they arise or whatever their type – are metastatic cancers. Metastasis means that the cancer has spread from the place where it started into other tissues distant from the original tumor site.
Does your body ache with breast cancer?

How do you feel physically when you have breast cancer?

- irregular or absent periods.
- shifts in mood.
- hot flashes.
- breast tenderness.
- headaches or accentuation of pre-existing migraines.
What causes estrogen breast cancer?
Some breast cancers develop due to a problem involving hormones, including estrogen and progesterone. These hormones play a role in telling breast cells to grow. In hormone receptor-positive breast cancer, the receptors for hormones cause breast cells to grow in an uncontrolled way.
What are symptoms of high estrogen?
