Phase 0, also called carcinoma in situ, is the first stage of breast cancer. This precancerous condition is a very early stage of breast cancer. Many stage 0 of breast cancers do not need treatment. When they do, the approach is usually very profitable.
At this stage, there is not any indication that the tumor cells have spread to other parts of the breast or another part of the human body. Often, stage 0 is precancerous conditions that require close observation, but not treatment.
Stage 0 breast cancer is hard to detect. At self-examination, there is almost no lump at all, and there may be no other symptoms. But, breast self-exams and routine screening are always significant and may often lead to early identification, when the cancer is most treatable. Stage 0 disease is most frequently found by accident in a breast biopsy for a different reason, such as to investigate an unrelated breast lump.
There are two kinds of stage 0 breast cancer:
1. Ductal Carcinoma In Situ (DCIS)
DCIS has become the most frequent type of non-invasive breast cancer. Occurs when breast cancer cells grow in the breast ducts. Now, it’s easy to find stage 0 DCIS more often because more women have regular mammogram screenings. DCIS can get invasive so that early treatment could be significant.
2. Lobular Carcinoma In Situ (LCIS)
LCIS increases a female’s risk for developing breast cancer, but it isn’t considered cancer. Occurs when abnormal cells grow in the lobules. These cells aren’t cancerous, and this disease seldom becomes curable cancer. However, women who create LCIS might be at higher risk for developing breast cancer later on. For women who build LCIS, the danger of growing an invasive cancer is 20 – 25 percent over 15 years after the initial diagnosis.
Stage 0 Breast Cancer Treatment
Remedies at this point aims to prevent the growth and spread of tumors, and the prognosis is quite good. Treatment for DCIS intends to stop it from developing into an invasive tumour. LCIS does not require treatment when there are no other strange changes in the breast.
Surgery is the primary treatment for DCIS. Most girls choose breast conservation surgery according to the doctor’s advice. If there are several areas of DCIS from the breast, doctors may do a mastectomy to be sure that all the cancer is gone. Doctors do not remove lymph nodes under the arm (called axillary lymph node dissection) to get DCIS because this cancer has not spread outside the duct at the breast.
To lower their risk of developing invasive breast cancer, some women should be closely monitored and might choose to have their breasts removed (called a prophylactic mastectomy).
External beam radiation therapy is generally given after breast-conserving surgery for DCIS. To reduce the risk of cancer returning (relapse) from the breast, doctors use this treatment, especially if there is high-grade DCIS. In rare cases, radiation therapy isn’t necessary because the DCIS is reduced grade, it is only in a tiny area of the breast, and the operation will eliminate it.
LCIS does not require radiation therapy.
Tamoxifen (Nolvadex, Tamofen) is provided for hormone receptor-positive DCIS. Hormone treatment starts immediately in women who suffer from this disease. It’s given for as much as ten years to decrease the risk that you will produce another breast cancer.
Doctors will give tamoxifen to women with LCIS to reduce the risk of invasive breast cancer will grow.
This means that almost all women with stage 0 breast cancer will survive for at least five years after receiving this diagnosis. In fact, women diagnosed with stage 0 breast cancer usually live long and wholesome lives.
