37 years old, Pre-menopausal, Stage1, Grade1

[JSH76]

I recently underwent a bilateral mastectomy after finding a tumor in my right breast.  The pathology of that tumor is below:
2 lymph nodes tested:  negative.
BRCA1 & BRCA2 tests:  negative.
Tumor size: 1.5cm
Tumor focality: Single focus of invasive carcinoma
Skin: doesn't invade into dermis or epidermis
Nipple and DCIS: DCIS doesn't involve the nipple epidermis
DCIS: DCIS is present and positive for EIC
DCIS dimensions: 2cm
Architectural patterns of DCIS: Solid
Nuclear grade of DCIS: Grade 2
Necrosis of DCIS: not identified
Lobular Carcinoma: Absent
Type of invasive carcinoma: Invasive ductal carcinoma (NOS)
Margins of DCIS: margins uninvolved by DCIS
Location closest margin: superior radial margin
Distance from closest margin: 2mm
Margins - Invasive: margins uninvolved by carcinoma
Location closest margin: superior radial margin
Distance from closest margin: 1mm
pTNM staging: pT1c, pN0, pM0.
Prognostic markers performed prior to case: Yes, S13-40089
Estrogen Receptor: 86%
Progesterone Receptor: 67%
Her-2/neu score: 0
Oncotype score:  11
My oncologist said that he doesn't pay attention to the Oncotype score because it's tests were done on 83% post-menopausal women, and since I'm pre-menopausal it didn't apply to me.  I was a bit discouraged at this.  He, even with the low Onco score, said he felt I needed chemo (seemed "bent" on chemo).  I'm a bit concerned about this and hoped you could provide some feedback.

I wish you had posted this as a new post so that more attention could be devoted to it .... you cannot compare one case with another and there are too many factors to take into consideration when formulating a treatment plan. Oncologists also differ in their methods of treatment. If you have questions regarding your treatment then I suggest that you obtain a second opinion from another Oncologist after he/she reviews all your reports. Chemo is always recommended if there is lymph node involvement and often even when the nodes are not involved. There is absolutely NO relation between your cancer and that of "JSH78" so you can't base any part of your treatment on hers.  Best wishes for a speedy recovery and successful treatment.   Regards .....

I had a lumpectomy and just completed radiation for a 1.5 cm lobular carcinoma.  My Oncotype score was 15 and my doctor advised against chemo as she said with this score, my recurrence rate was low and chemo would not help.  My cancer is estrogen receptive so I will be starting Tamoxifan soon.  I am pre-menopausal. Very curious about the differences in chemo recommendations.

Some Oncologists prefer an aggressive treatment method which of course is better than under treating a tumor. If you are totally against Chemo then you are certainly within your rights to obtain a second opinion from another Oncologist. Most Physicians are more than willing to offer a patient the opportunity of obtaining a second opinion. It just depends on how much confidence you have in your present Oncologist but any and all medical treatment is up to you to either accept or decline. Regards .....
