2. Possibilities of radiation methods in early
diagnosis of breast cancer

3. Breast cancer is the Most common cancer found in
women.
The early diagnos and the treatment is the most
important in breast cancer management as
organ preservance is also considered as most
important part of it.

4. From the traditional methods that have been
using since many years and to the new modern
techniques ,a lot has been changed since few
decades.
1.Mammography:it has been the gold standard
diagnostic methods and is proven to be much
helpfull in diagnosis of breast cancer
The findings on mammography that are been

6. Linked to breast cancer include nodular
formations with a hafazrad contours,the
presence of calcifications(usually in absence of
a defined mass )is more suggestive of breast
cancer.
There are few limitation as some histological
varients are difficult to find on mammograpgy.

8. 2.Xray tomosynthesis:it is advanced version of
mammography where we can get 3D images
by looking at the breast at different angles.this
helps us to understand the architecture of
tissues of breast in normal and pathological
scenerios.
This techniques is though costly but in many
develped countries this has been introduced in
screening programme.

10. 3.Xray Computed Tomography:
A much advanced technique in terms of
sensitivity and specificity as it not only helps
us in diagnosis but also plays an important role
in differentation different types of pathologies
in breast in relation to surrounding tissues eg
lymph nodes.

12. There are few limitations of the XRAY CT as like
poorly tissue differentiation in breast itself and
its high radiation exposure to the breast tissue.
4.The next ionising but NON invasive technique
includes PET scan:based on Tc99 this is been
nowadays used as one of the preferred
methods for breast cancer daignosis.

14. the mechanism by which PET can help us
includes the accumulation of TC99 inside the
neoplastic lesions and this helps us in
differentiating it from norma tissue.
PET can is also said to be having high axillary
node sensitivity but sometimes false negative
can also be seen in cases where lymph node
diameter <1 cm

16. NON INVASIVE AND NON IONISING TECHQ
This mainly includes the ultrasonographic
methods in looking the breast tissue masses.the
major benefit that is seen with USG is less
exposure of radiations,better visuality of
masses with granular tissue,high information
provided then mammography.

18. The new varients including the color doppler and
color duplex mapping are being used as they
have better sensitivity to different tissues
surrounding the breast.
