Accordingly, what is the pathology of breast cancer?
Pathology. Most breast cancers are epithelial tumors that develop from cells lining ducts or lobules; less common are nonepithelial cancers of the supporting stroma (eg, angiosarcoma, primary stromal sarcomas, phyllodes tumor). Cancers are divided into carcinoma in situ and invasive cancer.
Beside above, why is left breast cancer more common? Breast cancer is more common in the left breast than the right. The left breast is 5 - 10% more likely to develop cancer than the right breast. The left side of the body is also roughly 5% more prone to melanoma (a type of skin cancer). Nobody is exactly sure why this is.
Also, what are the causes of breast cancer?
Factors that are associated with an increased risk of breast cancer include:
- Being female.
- Increasing age.
- A personal history of breast conditions.
- A personal history of breast cancer.
- A family history of breast cancer.
- Inherited genes that increase cancer risk.
- Radiation exposure.
What breast cancer has the worst prognosis?
Certain breast cancer subtypes have a better statistical prognosis
|breast cancer sub-type||Estimated Overall Survival|
|Tubular breast carcinoma||almost 100% (15 year survival)|
|Infiltrating lobular carcinoma||90% (5 year survival)|
|Infiltrating ductal carcinoma||88% (5 year survival)|
|Medullary breast carcinoma||91% (10 year survival)|
