People diagnosed with stage 0, I or II breast cancers tend to have higher overall survival rates than people diagnosed with stage III or IV breast cancers. However, overall survival rates are averages and vary depending on a person's diagnosis and treatment.
Ductal carcinoma in situ (DCIS) is the earliest form of ductal carcinoma. "In situ" means it's only in the milk ducts, and isn't likely to spread to other parts of your body. About 1 in 5 people who are newly diagnosed with breast cancer have DCIS. This type is very curable.
Ductal carcinoma in situ (DCIS), is non-invasive breast cancer that has not spread outside the milk ducts where it started. DCIS isn't life threatening, but is considered a precursor to invasive breast cancer and increases the risk of developing an invasive breast cancer later in life.
Metastatic breast cancer (also called stage IV, stage 4, secondary breast cancer, or advanced breast cancer) has the poorest prognosis. This is when cancer has spread beyond the breast and nearby lymph nodes to create tumors in other parts of the body, such as the bones, lungs, liver, or brain.
Many people with localized or regional breast cancer survive for 20 years or longer after receiving a diagnosis and treatment. It is rare for someone with distant breast cancer to live for 20 years. However, scientists are continuing to improve treatments for distant breast cancer.
A woman is considered to have a high risk if she has at least a 1.67% chance of developing breast cancer in the next five years, or a lifetime risk of at least 20%.
The overall 5-year relative survival rate for breast cancer is 90%. This means 90 out of 100 women are alive 5 years after they've been diagnosed with breast cancer. The 10-year breast cancer relative survival rate is 84% (84 out of 100 women are alive after 10 years).
Triple-negative breast cancer (TNBC) is a rare type of breast cancer. It is harder to treat and much more aggressive. Because it is aggressive and rare, fewer treatment options are available. It also tends to have a higher rate of recurrence.
Although Stage 4 breast cancer is not curable, it is usually treatable and current advances in research and medical technology mean that more and more women are living longer by managing the disease as a chronic illness with a focus on quality of life as a primary goal.
Each year in the United States, about 264,000 cases of breast cancer are diagnosed in women and about 2,400 in men. About 42,000 women and 500 men in the U.S. die each year from breast cancer. Black women have a higher rate of death from breast cancer than White women.
With treatment, the prognosis (chances of survival) for young women diagnosed with early breast cancer are good. However, prognosis tends to be worse for women under 40 than for older women. This is because breast cancers in younger women can be more aggressive than breast cancers in older women [221].
In situ breast cancer cells are non-invasive and remain in a particular location of the breast, without spreading to surrounding tissue, lobules or ducts. Breast cancer that does not spread beyond the milk ducts or lobules is known as in situ. The two types of in situ cancers are ductal carcinoma and lobular carcinoma.
NONINVASIVE BREAST CANCER
“Ductal” refers to the milk ducts in the breast, and “in situ” means “in its original place.” DCIS is a stage 0 cancer, which is the earliest and generally the most treatable form of breast cancer.
What You Need to Know About Skipping Chemotherapy. Many women with hormone-positive, HER2-negative, lymph node-negative early-stage breast cancer who have intermediate risk of cancer recurrence do not need chemotherapy.
Metastatic breast cancer occurs at stage 4, when the disease has spread to other areas of the body, such as the brain, bones, lungs, and liver. Although this stage of breast cancer is not curable, it is usually treatable.
Triple-negative breast cancer (TNBC) is difficult to treat due to its aggressive nature. It often responds initially to chemotherapy but is the most common breast cancer to recur; when it recurs, it is more resistant to chemotherapy, making it less responsive and more challenging to treat.
Potential reasons behind this statistic include larger left breast size, more frequent self-screening of left breast, and right-side breastfeeding preferences.
Mastectomy for breast cancer treatment
A mastectomy may be a treatment option for many types of breast cancer, including: Ductal carcinoma in situ (DCIS), or noninvasive breast cancer. Stages I and II (early-stage) breast cancer. Stage III (locally advanced) breast cancer — after chemotherapy.
Most women (almost 100%) will survive their cancer for 5 years or more after diagnosis.
She survived for 18 years after the diagnosis of metastatic breast cancer (MBC) while maintaining a good quality of life. To the authors' knowledge, this is the first reported case in the literature with the longest overall survival in a patient with MBC.
Inflammatory Breast Cancer - a rare and aggressive type of invasive breast cancer. In this disease, cancer cells block lymph vessels in the skin of the breast.
Most breast cancers are found in women who are 50 years old or older. Some women will get breast cancer even without any other risk factors that they know of. Having a risk factor does not mean you will get the disease, and not all risk factors have the same effect.
Studies show that even though breast cancer happens more often now than it did in the past, it doesn't grow any faster than it did decades ago. On average, breast cancers double in size every 180 days, or about every 6 months.
