Location in the body that is affected and/or typical location where cancer develops: the breast

Causes/ Risk factors: lacking estrogen, progesterone hormones and HER2/neu

Symptoms: Lumps appear in the breast tissues and there might be a change in the breast or nipple.

Treatment: Radiation and chemotherapy are the two most common treatments in Triple Negative Breast Cancers. 

Chemotherapy works well with TNBC than in other types of breast cancer. The process shrinks the tumor enough 

so that a lumpectomy becomes an option.

Frequency of diagnosis: 15-20% of breast cancers in the United States are Triple Negative Breast Cancer. Younger 

women, African American women and women who have BRCA1 mutations tend to have this type of breast cancer.

Survival Rate: These cancer cells tend to spread in a wider range and faster than those of normal breast cancer cells. 

77% of women with Triple Negative Breast Cancer survived at least five years versus 93% of women 

with other types of breast cancers.

Location in the body that is affected: milk ducts and skin/tissue that line the breast

Causes/Risk factors: The cause is unknown but could be because of family history of breast cancer

those who had their period at early age, and women who have never had children

Symptoms: most women do not experience any symptoms whatsoever, but in few cases it may cause a lump or thickening near the breast of under the arm

Treatment: The main treatment is surgery. Sometimes wide local local excision is used followed by radiotherapy to the rest of the breast tissue if the cells look very abnormal (high grade). Others include mastectomy and tamoxifen to to reduce the risk of developing invasive breast cancer in the future

Statistics: 60,000 cases of DCIS a year, 1 out of every 5 breast cancer cases is DCIS

-Located in the milk producing lobules but eventually invades other tissues of the breast. It can also spread to lymph nodes or other organs.

-Causes include genetic mutations in DNA that replicate, but the specific cause of ILC is unclear. Risk factors include being a female of older age, postmenopausal hormone use and history of cancer in your family.

-Symptoms include thickening and hardening of the breast (not a distinct lump), area of fullness or swelling, a nipple turning inward, or a change in texture of the skin on the breast.

-The treatment includes surgery and radiation therapy, and systematic treatment such as chemotherapy, hormonal therapy, and target therapy.

- Statistics: About 10% of breast cancer is ILC

1 in 5% of breast cancers are inflammatory breast cancers.  

Symptoms- Inflammatory breast cancer usually starts with the reddening and swelling of the breast instead of a distinct lump. IBC tends to grow and spread quickly, with symptoms worsening over a course of a few days or even hours. The average age at diagnosis for inflammatory breast cancer in the United States is 57 for white women and 52 for African American women. These ages are about 5 years younger than the average ages at diagnosis for other forms of breast cancer. 

According to the American Cancer Society, inflammatory breast cancer is more common in African American women. A study in 2008 found that being overweight makes a person more likely to develop IBC. Like other forms of breast cancer, IBC can also affect men.
