Stage 0 Breast Cancer: What’s It All About, Symptoms, and How to Treat It
Stage 0 breast cancer is the earliest form of breast cancer you can get. It’s when cancer cells are present but haven’t spread anywhere else.
Known as ductal carcinoma in situ (DCIS), stage 0 is basically the baby stage of breast cancer. At this point, the cancer hasn’t started spreading, so it’s not life-threatening. However, it can turn into more serious breast cancer if not taken care of. That’s why knowing about stage 0 breast cancer, keeping an eye out for any symptoms, and getting an early diagnosis are super important. Regular check-ups, mammograms, and self-exams are crucial for all women. Let’s dive into what stage 0 breast cancer is all about and how to get it checked and treated.
What’s Stage 0 Breast Cancer?
According to the American Cancer Society, about 20% of all breast cancers are stage 0. It’s also called ductal carcinoma in situ (DCIS) and is basically the earliest form of breast cancer. Dr. Garvit Chitkara explains it’s when you have abnormal cells inside the milk ducts of your breast, but they haven’t spread to nearby tissue or anywhere else in the body.
Is Stage 0 Breast Cancer Dangerous?
DCIS isn’t life-threatening on its own since it’s non-invasive. But if you don’t treat it, it could turn into invasive breast cancer, which can spread and become harder to treat. That’s why it’s often called a ‘pre-cancerous’ condition. Cancer Research UK says it’s pre-invasive, meaning it hasn’t broken out of the ducts and invaded other breast tissue.
Symptoms of Stage 0 Breast Cancer
The tricky part about stage 0 breast cancer is that it usually doesn’t show any symptoms. Most cases are spotted during a routine mammogram, where doctors find tiny calcium deposits called microcalcifications. Dr. Chitkara points out that since it’s non-invasive, it typically doesn’t cause pain or lumps. In rare cases, you might notice a lump or unusual nipple discharge, but that’s not common for stage 0.
Types of Stage 0 Breast Cancer
There are two main types:
- Ductal Carcinoma in Situ (DCIS): Abnormal cells are found in the lining of the breast ducts.
- Paget Disease of the Nipple: Abnormal cells are in the skin cells of the nipple and might spread to the areola. Sometimes, people with this also have DCIS or invasive breast cancer in the same breast.
Do You Need to Treat Stage 0 Breast Cancer?
Yep, treatment is generally recommended to keep it from turning into invasive cancer. Dr. Chitkara says the goal is to get rid of the abnormal cells before they spread. Treatment options usually include surgery, like a lumpectomy (removing the abnormal tissue plus a bit of healthy tissue) or a mastectomy (removing one or both breasts), depending on how much DCIS there is and where it’s located.

Do You Need Radiation for Stage 0 Breast Cancer?
-
After surgery for stage 0 breast cancer, you might need radiation therapy to zap any remaining cancer cells and cut down the chances of it coming back. But here’s the thing: according to the American Cancer Society, a lot of women don’t need radiation after a mastectomy for stage 0 cancer. Even though DCIS isn’t life-threatening, treating it is still important because if left untreated, it could increase the risk of developing more serious breast cancer later on.
Can You Just Wait and See with Stage 0 Breast Cancer?
Not really. Dr. Chitkara says that taking a ‘wait and watch’ approach isn’t usually recommended for Stage 0 breast cancer. Unlike some other conditions, DCIS can turn into invasive breast cancer, which can spread and become tougher to deal with. Even though it doesn’t always progress, the risk is high enough that doctors usually suggest starting treatment right away.
For a few patients with very low-risk DCIS, there might be some more relaxed management options through clinical trials or expert advice, but that’s not the standard way of handling it, according to Dr. Chitkara.
Who’s at Higher Risk for Stage 0 Breast Cancer?
Some people have a higher chance of getting Stage 0 breast cancer. Here are some factors that might bump up your risk:
- Family History: If you have a strong family history of breast cancer, especially if close relatives got it at a young age, you’re at higher risk. Genetic mutations like BRCA1 and BRCA2 also raise your chances of both DCIS and invasive breast cancer.
- Personal Breast History: If you’ve had breast conditions like atypical hyperplasia.
- Previous Radiation: If you had radiation therapy to your chest, especially when you were younger.
- Menstruation and Pregnancy: Starting your period early or going through menopause early can increase your risk. Also, having your first baby after 30 might up the odds.
- Hormone Therapy: Using hormone replacement therapy after menopause can be a risk factor.
- Lifestyle Factors: Things like obesity, drinking alcohol, and not getting enough exercise can also increase your risk.
What’s Next After Stage 0 Breast Cancer?
Once you’ve had your initial treatment for Stage 0 breast cancer, follow-up care is key to keep an eye out for any signs that it might come back or for new breast cancer. Dr. Chitkara says this usually means regular check-ups and imaging tests like mammograms to spot any changes in your breast tissue.
If your DCIS was hormone receptor-positive, you might be prescribed hormone therapy (like tamoxifen or aromatase inhibitors) for 5 to 10 years to lower the chances of it coming back. Your follow-up plan will be tailored to the specifics of your treatment, the nature of your DCIS, and your personal risk factors. The main goal here is to catch any issues early when they’re easier to treat and to keep you supported in maintaining your breast health.
