7. TREATMENT
The treatment modes available for Cancer
Breast are:
1. Surgery
2. Radiotherapy
3. Chemotherapy
4. Hormonal therapy
*
Surgery is reserved for early cancer breast in cases of stage
I(T1 No) and stage II(T1, T2, N1).
The operations in use today are:
1. Radical Mastectomy (Halstead)
This procedure is aimed at
removing the whole breast the
underlying Pectoralis major and minor and
the regional
lymph nodes along
the axillary vein.
No prosthatic
reconcentration is possible after
the chest wall muscles
have been removed.
2. Modified Radical Mastectomy
(Patey's)
In this procedure all the
structure accept the Pectoralis
Major are removed
3. Modified Radical Mastectomy
(Maddon's)
In this procedure the pectoralis
minor is divided but not
removed
4. Simple Mastectomy and
clearance of lymphnodes from the
axilla
The skin incision is eliptical
and starts at over rectus
sheath and includes the nipple and the upper end is above
the margin of the pectoralis
major. Both upper flap are
mobilised till the upper and lower limits of breast tissue
are expanded. The breast tissue
(and nipple) are directed
off the pectoralis major. The later end of the incision
allows excessing axillary lymph nodes.
5. Wide local
excision of the tumour with preservation
of
breast followed by radiation.
The
surgical procedure is dependent on the
surgeons preference
and
the clinical stage of the disease. There is a
trends to
choose a less radical procedure among
surgeons today.
*
Chemotherapy and hormone therapy (adjuvant therapy)is added to
surgery in cases of Stage II.
It
has been shown that chemotherapy
has benefitted both those
with
nodes and those without nodes.
Tomoxifen has also been of benefit
to receptor positive and receptor poor tumours when the
patient is over 50 years.
