Chemo, r, and anti hormonal, after a successful lumpectomy?

annie007

Why do I need Chemotherapy, Radiation, and anti hormonal Therapy after a successful  lumpectomy and  the lab results were free of cancer?

The third week of december I had a lumpectomy and a biopsy of two lymph nods. The diagnosis was:

1. Sentinel Lhymph  Node #1, Biopsy:  - Two Lymph Nodes negative foe metastatic tumor, 0/2 (By H&E stain and  Pankeratin Immunohistochemical stains on blocks 1A-B).

2. Nonsentinel Lymph Node, right biopsy: - One Lymph Node Negative for Metatatic Tumor, 0/1.

3. Breast, right needle localization lumpecyomy:

- Ivasive Ductal carcinoma ( tumor site not specified)

- Biopsy site changes present.

- Remaining Breast Parenchyma with focal usual-Type ductal hyperplasia.

- Skin without diagnostic abnormality.

- Tumor size: 2.2 cm

- Glandular  (Acinar) / tubular diffrenciation: score 3

- Nuclear Plemorphism: score 2

- Mitotic rate: score 1

Overall grade: Grade 2

Tumor focality: single focus of invasive carcinona

Ductal carcinona In Situ (DCIS is present)

Negative for extensive intraductal component (EIC)

size (extent) of DCIS:

Estimate size  (extent) of DCIS (greatest dimension using gross and microscopic evaluation): at least 0.4 cm

Number of blocks with DCIS: 1

Number of blocks examined: 9

Architectural patterns: Cribriform

Nuclear grade: grade II (Intermediate).

Lobular carcinoma In Situ (LCIS)" Not identified

Macroscopic and microscopic extent of tumor:

skin: invasive carcinoma does not invade into the dermis or epidermis.

Nipple: Not applicable

Skeletal Muscle: Not applicable.

I was told by the radiologist that I have a 15% to 20%  chance to get cancer again in 10 to 15 years without treatment, and I will have 5%  of getting cancer again with treatment  in 10 to 15 years. I feel that 5% to 20% with or without treatment is worth to wait  for treatment until I  get the cancer again if I get it. 

The radiologist explained two options: #1. radiation for 6 weeks  that could be reduced to  4 weeks. #2 Breast Breachytherapy for 5 days.

The Oncologist offered  a must have the following plan:  #1 chemotherapy for 4 months in cycles of 1 day every 3 weeks. then #2  radiation from radiolist. then #3 anti hormonal  replacemetn therapy.

The radiologist  disagreed with that, he really wants option # 2. He called my surgeon already and the surgeon nurse called me  telling me that the surgeon wants the #2 option (radiologist) to be done next week. I fell that I need more information before making a decision. Please help me with more information. Thank you,  Annie
