What is the most common type breast cancer?

What is the easiest breast cancer to treat?

Ductal carcinoma in situ or DCIS

The cancer cells have not spread through the walls of the ducts into the nearby breast tissue. Nearly all women with DCIS can be cured.

What type breast cancer has the highest recurrence rate?

Research suggests that estrogen receptor-positive breast cancer is more likely to come back more than five years after diagnosis. In this study, the researchers looked at the risk of late breast cancer recurrence, meaning the breast cancer came back 10 or more years after diagnosis.

What is the least aggressive type of breast cancer?

Luminal A — the least aggressive and most common subtype — accounts for 42% to 59% of all breast cancers, according to background information in the study. Luminal B typically occurs in younger women and accounts for about 10% of all breast cancers.

What is an aggressive breast cancer?

Triple-negative breast cancer (TNBC) is considered an aggressive cancer because it grows quickly, is more likely to have spread at the time it’s found, and is more likely to come back after treatment than other types of breast cancer. The outlook is generally not as good as it is for other types of breast cancer.

Is HER2 positive breast cancer more aggressive?

This protein promotes the growth of cancer cells. In about 1 of every 5 breast cancers, the cancer cells have extra copies of the gene that makes the HER2 protein. HER2 -positive breast cancers tend to be more aggressive than other types of breast cancer.

What is the best type of breast cancer to have?

Tubular ductal carcinoma is a rare diagnosis of IDC, comprising only 2% of breast cancer diagnoses. The name comes from how the cancer looks under the microscope — like hundreds of tiny tubes. Tubular breast cancer has an excellent prognosis.

Is it better to be HER2-negative or positive?

Breast cancer cells with higher than normal levels of HER2 are called HER2-positive. These cancers tend to grow and spread faster than breast cancers that are HER2-negative, but are much more likely to respond to treatment with drugs that target the HER2 protein.

What stage of breast cancer requires a mastectomy?

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.

Which is worse ductal or lobular cancer?

Invasive Lobular Breast Cancer May Have Worse Prognosis than Ductal Cancer.

Is Stage 3 lobular breast cancer curable?

With aggressive treatment, stage 3 breast cancer is curable; however, the risk that the cancer will grow back after treatment is high.

Do you need chemo for invasive lobular carcinoma?

Your treatment options for invasive lobular carcinoma depend on the aggressiveness of your cancer, its stage, your overall health and your preferences. Treatment often consists of surgery and additional (adjuvant) therapy, which may include chemotherapy, radiation and hormone therapy.

What stage of breast cancer is invasive ductal carcinoma?

Generally, the stage of invasive ductal carcinoma is described as a number on a scale of I through IV. Stages I, II, and III describe early-stage cancers, and stage IV describes cancers that have spread outside the breast to other parts of the body, such as the bones or liver.

What is the life expectancy of invasive ductal carcinoma?

The five-year survival rate is quite high — almost 100 percent when the tumor is caught and treated early. Once the cancer has metastasized to distant organs like the bones or liver, the five-year survival rate drops by almost three fourths.

How long does it take for invasive ductal carcinoma to spread?

Each division takes about 1 to 2 months, so a detectable tumor has likely been growing in the body for 2 to 5 years. Generally speaking, the more cells divide, the bigger the tumor grows.

What is the survival rate for invasive ductal carcinoma stage 2?

99 percent for localized breast cancer (has not spread outside the breast) 86 percent for regional breast cancer (spread to nearby lymph nodes)

How treatable is invasive ductal carcinoma?

Invasive ductal carcinoma is quite curable, especially when detected and treated early.

What is the treatment for invasive ductal carcinoma grade 2?

Stage II cancers are treated with either breast-conserving surgery (BCS; sometimes called lumpectomy or partial mastectomy) or mastectomy. The nearby lymph nodes will also be checked, either with a sentinel lymph node biopsy (SLNB) or an axillary lymph node dissection (ALND).
