Hello, thank you for sharing your concern. Based on the details you provided, your doctors’ recommendation may actually be medically reasonable and reassuring.
You had: - High-grade DCIS (ductal carcinoma in situ / comedocarcinoma) - No invasive carcinoma found - Total mastectomy already performed - Skin and nipple uninvolved - No evidence of spread described
DCIS is considered a “stage 0” breast cancer because the abnormal cells remain confined inside the ducts and have not invaded surrounding tissue.
In many cases, when:
- a complete mastectomy has been done, - margins are clear, - and no invasive cancer is present,
additional chemotherapy is often NOT needed because chemotherapy mainly targets invasive/systemic disease.
Radiation is also commonly unnecessary after total mastectomy for pure DCIS unless there are unusual high-risk features or incomplete excision.
The “unusual” part your doctor mentioned may relate to: - high-grade pathology despite no invasion, - or the overall pathology pattern, but that does not automatically mean undertreatment.
What is important now: - Continue regular oncology follow-up - Keep all pathology reports safely - Continue routine surveillance of the opposite breast - Discuss whether hormone receptor testing (ER/PR status) was done and whether hormonal therapy is relevant in your specific case
You may also consider a second opinion from a breast oncologist/pathologist if it would give you peace of mind, especially because the pathology was described as unusual.
Seek medical review if you notice: - New breast/chest wall lumps - Swelling - Unexplained weight loss - Persistent bone pain - New skin changes
Final Prescription / Advice: - No self-medication or unnecessary cancer treatments without oncology guidance - Continue scheduled oncology surveillance and breast follow-up - Maintain healthy diet, exercise, and avoid smoking/alcohol if applicable
Advice: Based on the information provided, a mastectomy alone can be sufficient treatment for non-invasive high-grade DCIS when no invasive cancer is found, but continued oncology follow-up remains essential.
Feel free to reach out again.

Given your situation, it’s understandable to have questions about what comes next after a high-grade DCIS diagnosis and mastectomy. First and foremost, continue with regular follow-up appointments with your healthcare team. These check-ins are crucial for monitoring any potential recurrence or complications post-surgery. Your doctor’s recommendation that no further treatment is needed likely stems from the effective removal of the affected breast tissue and lack of invasive carcinoma. However, staying vigilant and adhering to follow-up schedules is key.
Consider discussing with your clinician about a personalized surveillance plan that may include physical exams and imaging tests like mammograms or MRIs to keep an eye on your remaining breast, if you haven’t already had a bilateral mastectomy. Although you’ve not undergone lymph node dissection or further treatment, it’s also worth reviewing any lifestyle factors that may support your overall breast health and reduce future cancer risks. This might encompass maintaining a healthy diet, regular physical activity, limiting alcohol intake, and managing your weight. If you have a family history of breast cancer, discuss with your doctor the possibility of genetic counseling or testing for mutations like BRCA1 or BRCA2, which could influence your risk-reduction strategies.
Stay aware of any new or unusual symptoms and report them promptly. Consider also engaging with a support group or network—connecting with others who have had similar experiences can provide insights and additional information. Lastly, always feel empowered to seek a second opinion if you have lingering concerns about the absence of further treatment; another specialist might offer additional insights. Pursue these strategies while keeping in close partnership with your healthcare provider to ensure a proactive approach tailored to your health and circumstances.
Hello dear See as per clinical history it seems ductal carcinoma in situ As per clinical history Surgical mastectomy has already been completed. So there are less chances of reoccurrence However There is no requirement of Chemotherapy Radiotherapy But fir clinical evaluation and clarity Follow up with concerned physician only for better clarity Hopefully you recover soon Regards
Hello Thank you for sharing your history so clearly. Here’s a simple explanation of your situation and what it means for you:
What your diagnosis means: - You had ductal carcinoma in situ (DCIS), which is a non-invasive form of breast cancer. It means the cancer cells were confined to the ducts and had not spread into surrounding breast tissue. - The high-grade comedocarcinoma type is more aggressive, but still non-invasive. - Your mastectomy removed all breast tissue, and there was no evidence of invasive cancer—so the cancer hadn’t spread beyond the ducts. - Skin and nipple were unaffected, and no lymph nodes were involved.
Why your doctor says you don’t need further treatment: - Since DCIS is non-invasive and your mastectomy removed all affected tissue, the risk of recurrence is extremely low. - No lymph node involvement means there’s no sign the cancer has spread. - Chemotherapy and radiation are usually reserved for invasive cancers or when there’s a risk of spread, which you don’t have.
What you should do next: - Regular follow-up: Keep seeing your doctor for routine check-ups. They’ll monitor for any signs of recurrence or new issues. - Self-care: Watch for any changes in your remaining breast tissue, skin, or general health. - Healthy lifestyle: Eat well, stay active, and avoid smoking or excessive alcohol.
Alternatives and additional steps: - If you’re worried or want extra reassurance, you can ask for a second opinion from another oncologist. - Some people choose to have genetic testing (like BRCA) if there’s a family history, but it’s not always necessary.
Your case is unusual because high-grade DCIS is aggressive, but mastectomy is very effective. You’re in a good position, and ongoing monitoring is all that’s needed. If you notice any new symptoms or have concerns, reach out to your doctor.
Thank you
Namaste 🙏
First, I want to acknowledge your strength through this journey. You’ve been through significant surgery and uncertainty — let me provide clarity.
🔍 Understanding Your Diagnosis
· DCIS (Stage 0) — Cancer cells confined inside milk ducts, did not invade surrounding breast tissue · High-grade / Comedocarcinoma — Faster-growing subtype, but still non-invasive · Total Mastectomy — Entire breast removed, including all ductal tissue · Clear margins + no invasion + skin/nipple spared — Cancer fully removed
✅ Why No Further Treatment May Be Correct
· Mastectomy for pure DCIS = definitive treatment in most cases · No invasive cancer found = no need for chemotherapy · No lymph node involvement = no need for radiation in many DCIS protocols · Negative margins = local recurrence risk very low (~1-2% after mastectomy) · Your doctor called it “unusual” likely because high-grade DCIS often prompts radiation — but mastectomy changes the equation
🩺 What You Should Do Now
· Get a second opinion from a Medical Oncologist at a major cancer center — this is your right, and it will give you peace of mind · Ask directly: “Are my margins completely clear? What is my recurrence risk percentage?” · Request a copy of your full histopathology report and margin status · Discuss if Tamoxifen / Hormone therapy is recommended if your DCIS is hormone receptor-positive (reduces risk in remaining breast and opposite breast)
📋 Your Follow-Up Plan Going Forward
· Clinical breast exam of remaining breast every 6 months · Annual mammogram + ultrasound of the healthy breast · Monthly self-breast exam — learn from your surgeon · Healthy lifestyle — weight management, exercise, limit alcohol · Report any new lump, skin change, or pain immediately
💛 Reassurance
· Prognosis after mastectomy for pure DCIS = excellent, near-normal life expectancy · No chemo, no radiation needed when mastectomy achieves complete removal · You are not “undertreated” — you received definitive, appropriate treatment
You are a survivor, not just a patient. A second opinion will confirm what your doctor said — then you can fully focus on healing and moving forward.

Your pathology description is most consistent with Ductal Carcinoma In Situ, specifically a high-grade comedo-type DCIS that remained non-invasive, which means the abnormal cells were confined inside the milk ducts and had not spread into surrounding tissue. After a total mastectomy with clear margins and no invasive cancer, many patients do not require chemotherapy or radiation because the risk of recurrence becomes very low, so your doctor’s recommendation can be appropriate even though the pathology appears aggressive under the microscope. You should continue close follow-up with your breast surgeon or oncologist, ask for a detailed review of the final pathology report (including surgical margins and hormone receptor status if tested), and consider a second opinion from another breast oncology specialist if you feel uncertain or want reassurance about the treatment plan.
