Should I be worried
about breast cancer
Breast cancer has accounted for over
17% of deaths in women. Depending on its severity, there are five
stages of breast cancer.
-
In stage I, where the lump cannot be
felt but can be diagnosed by a mammogram, the 5-year survival rate is 95%.
-
In stage II, where the malignant lump
has not spread to the lymph nodes under the arm but has remained localized
to one breast and is smaller than 2 cm, the 5-year survival rate is 85%.
-
In stage III, where the growth of the
lumps is 2-5 cm and the lumps have not spread to the lymph nodes, the 5-year
survival rate is 66%.
-
In stage IV, where the growth of the
lumps is over 5 cm or the lumps have grown into the skin, the distant lymph
nodes or into the chest wall, the 5-year survival rate is 41%.
-
In stage V, where the malignancy has
spread to other parts of the body, the 5-year survival rate is 10%.
