2. CANCER
A disease that is characterized by uncontrolled cell growth in an
organ, the site the cells originate from.
BREAST CANCER
Begins in the breast tissue and may start in the duct or lobe of
the breast. When the "controls" in breast cells are not working
properly, they divide continually and lump or tumor is formed.
3. INCIDENCE
30% of all female cancers
20% of cancer related deaths in females
2-4% bilateral
2-5% hereditary
Lump in the breast-most common presentation (75%)
10% presents with pain
35-45% with mutation of BRCA1 gene 70% blood spread
occurs to bones
Incidence in India is one in 100 women.

35. Early Breast Cancer
(Stage I & II)
Surgery
removing the area of concern and some normal tissue
surrounding it is ca
ll
ed a lumpectomy
removing the breast is ca
ll
ed a mastectomy (most women
with breast cancer wi
ll
not need the breast removed )
lymph nodes
fr
om under the arm may be removed with
either surgery
36. I- Surgery

2. Traditional mastectomy + late breast reconstruction
2. Breast Conservative Surgery (B.C.S):
Indications:
1. Tumor < 4cm
2. No multi-centricity
3. Peripheral location
37. Mastectomy
A. Traditional Non Sparing Mastectomy
1. Super (Extended) radical (Urban)
2. Radical mastectomy (Halstedt)
3. Modi
fi
ed radical mastectomy

38.
39. Indications of
BREAST CONSERV
ATION THERAPY
1. Single tumor (no multi-centricity)
2. Tumor size <<4 cm (clinically & mammography)
3. Peripheral location (not central or retroareolar)
4. No signs of local advancement (T4).
5. No or N1 (no extensive nodal involvement).
6 Mo (no metastasis)
40. Contraindications
1. Multi-centricity - high incidence of local recurrence
2. Tumor size =/> 4 cm or increased tumor/breast ratio.
3. Central (retroareolar) location - bad cosmetic
result.
4 Signs of local advancement (T4).
5. N2 or N3
6. Metastasis (M1).
7. Pregnancy (3rd trimester; radiotherapy can not be
delivered)
8 Collagen vascular disease - high toxicity of
radiotherapy.
41. Early Breast Cancer
(Stage I&II)
Radiotherapy
standard treatment a
ft
er a
lumpectomy to reduce the
chance of the breast cancer
coming back in the same
breast
is also ca
ll
ed local treatment
because it a
ff
ects only the area
being treated with radiation
42. II- Adjuvant (postoperative)therapy
1.
Radiotherapy:
Indications:
1. After all cases of B.C.S. (must be taken within one month to
tumour bed and remaining part of breast)
2. After mastectomy (must be taken within 6 months); if:
- Tumor =/> 4 cm
- >4 +ve L.N. or extra-nodal disease
- Grade III
- Lymphovascular emboli (invasion)
43. II.
Systemic Therapy: Choice is according to:
1. L.N. status
. - ve L.N.
◦ Low risk - No systemic therapy
◦ Tumor < 1 cm
◦ Grade I
◦ ER +ve
Age > 35 years
o Moderate or high risk - systemic
therapy
II. +ve L.N. -Systemic therapy
44. Axillary Surgery in Breast Cancer
1-Axi
ll
ary lymph node dissection (ALND):
At least levels I & II axillary lymph nodes should be
removed
2- Sentinel L.N. biopsy:
Sentinel L.N. = 1st L.N. to drain the cancer
accepted with clinically negative axillary L.N.
3-Axi
ll
ary L.N. sampling:
Excision of the lowest 4 or 5 palpable L.Ns from level I &
sent separately for histopathologic examination.
45. First
Neo adjuvant chemotherapy (3-4 cycles)
Then
Surgery
Then
Post operative chemotherapy (6 cycles)
Then
Post operative radiotherapy
Late Breast Cancer
Stage III(locally Advanced)
46. Late Breast Cancer
Stage IV (Metastatic)
1- Pa
ll
iative systemic therapy is the Main line of treatment
47. 2- Surgery:
1. For primary tumor -Palliative Toilet Mastectomy
(as simple mastectomy), but indicating only in
ulcerating and fungating tumors with infection.
2. For metastases -
• Laminectomy for spinal cord compression.
• Internal
fi
xation of pathological long bone
fractures.
• Pleurodesis (chest tube + intrapleural Bleomycin)
for malignant pleural e
ff
usion.
48. - Growth of many breast cancers can be blocked
by taking hormone therapy.
- Treatment is in the form of pill which is taken
for 10 years.
- May be recommended for women who have a
breast cancer that is sensitive to hormone.
