Stage 0 Breast Cancer: Surgery and Recovery Rates - Oncology

Ductal Carcinoma In Situ (DCIS)


Hello Doctor: A relative has been diagnosed with stage 0 breast cancer, but the pathologist mentioned that more precise tests can only be done after surgery (mastectomy), so the symptoms are not yet fully confirmed.
I am a bit worried and would like to know what the cure rate is after surgery for breast cancer and if it is possible to achieve a "complete" recovery.

Hello: 1.
The biopsy confirmed stage 0 breast cancer, and the exact stage can only be determined after surgery.
2.
The cure rate is related to the stage; some recent studies show that for stages 1-2, the 10-year survival rate can reach 70%-85%, while for stages 3-4, it is approximately 20%.
3.
There is a possibility of complete recovery, but predicting recurrence is difficult, and physicians cannot guarantee it.
However, many patients have not experienced recurrence even after 10 or 20 years until their natural death.
Sincerely, Dr.
Chen Sih-Rong, Oncology.

Understanding Stage 0 breast cancer, also known as ductal carcinoma in situ (DCIS), is crucial for patients and their families. Stage 0 indicates that the cancer cells are confined to the ducts of the breast and have not invaded surrounding breast tissue. This early stage of breast cancer is often detected through mammograms or breast biopsies, and while it is not life-threatening, it does require careful management.

When it comes to surgical intervention, the most common treatment for Stage 0 breast cancer is a lumpectomy, where the tumor and some surrounding tissue are removed. In some cases, a mastectomy may be recommended, especially if the DCIS is extensive or if the patient has other risk factors. The choice of surgery will depend on various factors, including the size and location of the tumor, the patient's preferences, and the recommendations of the healthcare team.

The prognosis for Stage 0 breast cancer is generally very favorable. According to recent studies, the five-year survival rate for patients with DCIS is nearly 100%. This high survival rate is primarily due to the fact that the cancer has not spread beyond the ducts. After surgery, many patients will undergo additional treatments, such as radiation therapy or hormone therapy, depending on the specific characteristics of the cancer and the surgical margins. These treatments aim to reduce the risk of recurrence.

Regarding the question of whether a patient can achieve "complete" recovery, it is important to understand that while many patients do not experience a recurrence after treatment, there is no absolute guarantee. Factors that can influence the likelihood of recurrence include the tumor's grade, hormone receptor status, and the adequacy of surgical margins. Patients with low-grade DCIS and clear margins are at a lower risk of recurrence compared to those with high-grade tumors or close margins.

In terms of recovery, most patients can expect to return to their normal activities within a few weeks after surgery, although this can vary based on individual circumstances and the type of surgery performed. Follow-up care is essential, and patients will typically have regular check-ups to monitor for any signs of recurrence and to manage any long-term effects of treatment.

It is also worth noting that the emotional and psychological aspects of a breast cancer diagnosis can be significant. Patients and their families may experience anxiety and uncertainty, which is completely normal. Support from healthcare providers, counseling services, and support groups can be beneficial in navigating these feelings.

In conclusion, Stage 0 breast cancer has an excellent prognosis, with high survival rates and the potential for complete recovery. While the risk of recurrence exists, many patients go on to live healthy lives after treatment. It is essential for patients to have open discussions with their healthcare team about their treatment options, follow-up care, and any concerns they may have regarding their diagnosis and recovery.
