Early Detections reduces the risk of dying from breast cancer.
Cancer Diagnosis: Defining the Cancer The first step in designing the treatment plan is carefully defining the cancer –Clinical examination –Radiology tests –Pathology tests –Blood tests
Breast Cancer Signs and Symptoms None Lump or mass Pain in breast Tenderness Thickening Firmness Nipple discharge Skin redness Asymmetry Enlargement Nipple retraction Dimpling Mass in axilla (armpit) Warmth
Breast MRI Important new tool for imaging the breast High sensitivity Detection and characterization of otherwise- occult breast carcinoma
Breast Cancer Diagnosis Any breast change or lump needs to be evaluated Breast cancer needs to be diagnosed by biopsy –Fine needle aspiration –Core needle biopsy –Surgical biopsy
Mammotone & Minimally Invasive Breast Biopsy (MIBB) The Mammotone and MIBB are different from the core needle biopsy in that a needle is inserted once and multiple specimens are removed through contiguous sampling. Core needle biopsies require the needle to be inserted multiple times. Both the Mammotone and MIBB biopsy utilize a vacuum system. A probe is inserted and samples of tissue are collected in a chamber. Tissue samples are removed by action of a gentle vacuum.
Advantages of Needle Biopsies Simple procedure – does not require surgery Accurate Quick – only takes a few minutes Not painful Inexpensive Quick results
Disadvantages of Needle Biopsies Entire lump is not removed Open biopsy may be necessary For Fine Needle Only: Specialist needed to read results In situ cancer not distinguishable from invasive cancer
Image Guided Biopsy in Clinical Practice Allows treatment planning Better cosmesis Can mark site with clip Less costly Needs specialized equipment May still require confirmatory pathology in minority of cases
Breast Biopsy A core needle biopsy of the area is recommended Non- Surgical Surgical

Needle Biopsies Fine Needle – A thin, hollow needle is used to remove a sample of tissue. The procedure is quick and can be done in a doctor’s office. Core Needle – A larger needle is inserted through a small incision in the skin, and a small core of tissue is removed. This type of needle biopsy is done with the assistance of mammography or ultrasound imaging using stereotactic techniques with the aid of the computer, which calculates the precise location of the lump.
Incisional Biopsy A surgical procedure where only a portion of a tumor is removed Generally reserved for lumps that are larger Performed under local anesthesia in a hospital or outpatient clinic
Excisional Biopsy A surgical procedure that removes the entire suspected area plus some surrounding normal tissue. Standard procedure for lumps that are smaller than an inch or so in diameter Similar to a lumpectomy Performed under local anesthetic or general anesthesia in a hospital or outpatient clinic
Advantages of Open Biopsies Quick – takes only one hour More accurate than a needle biopsy Larger samples provide information for treatment plan Excisional Only: Removes entire lump May be the only surgical treatment needed
Disadvantages of Open Biopsies Surgical procedure Expensive Side effects such as infection or blood collection under the skin Excisional Only: Removing tissue can change the look and feel of the breast
Breast cancer Spread to lymph nodes Supraclavicular Subclavicular Distal (upper) axillary Central (middle) axillary Proximal (lower) axillary Mediastinal Internal mammary Interpectoral (Rotter’s)
Breast Cancer: Stage I T1a: T 0.5 cm T1b: 0.5 cm < T 1 cm T1c: 1 cm < T 2 cm T1 N0 M0 T 2 cm T1 N0 = no regional lymph node metastasis M0 = no distant metastasis
Breast Cancer: Stage IIA T2 N0 M0 N1 = metastasis to movable ipsilateral axillary lymph node(s) M0 = no distant metastasis 2 cm < T < 5 cm No evidence of tumor T0 T0T1 N1 M0 } T2
Breast Cancer: Stage IIB T3 N0 M0 N1 = metastasis to movable ipsilateral axillary lymph node(s) (p) N1a, N1b M0 = no distant metastasis T > 5 cm T2 N1 M0 T3
Breast Cancer: Stage IIIA Metastasis to ipsilateral axillary lymph node(s) N1 = movable N2 = fixed to one another or to other structures M0 = no distant metastasis T3 N1 M0 T0T1T2T3 N2 M0
Breast Cancer: Stage IIIB Any T N3 M0 N3 = metastasis to ipsilateral internal mammary lymph node(s) M0 = no distant metastasis Tumor of any size with direct extension to chest wall or skin T4d = inflammatory carcinoma T4 any N M0 T4
Breast Cancer: Stage IV M1 = distant metastasis (including metastases to cervical, or contralateral internal mammary lymph nodes) Any T any N M1
FDG PET scan Bone Scan Staging for Distant Disease: Breast Cancer Tumor in the breast, but not elsewhere Multiple bone metastases Patient A Patient B The most common sites of distant disease in breast cancer are the bones, liver and lungs
