Breast Cancer Classification


1. Invasive Ductal Carcinoma


  • Invasive Ductal Carcinoma is most common breast cancer type originating in milk ducts and spreading to surrounding breast tissue.
  • Accounts for approximately 80% of all breast cancer diagnoses in women.
  • Requires comprehensive medical intervention and personalized treatment strategies.

2. Invasive Lobular Carcinoma


  • Cancer beginning in milk-producing lobules and potentially spreading to adjacent breast tissues.
  • Invasive Lobular Carcinoma Represents about 10-15% of all breast cancer diagnoses.
  • Often more challenging to detect through standard mammography techniques.

3. Triple-Negative Breast Cancer


  • Triple-Negative Breast Cancer is an aggressive cancer subtype lacking typical hormone receptors and HER2 protein.
  • More common in younger women and certain ethnic populations.
  • Requires specialized treatment approaches and targeted therapeutic interventions.

4. HER2-Positive Breast Cancer


  • HER2-Positive Breast Cancer characterized by elevated HER2 protein levels promoting rapid cell growth.
  • Responds well to specific targeted therapies and advanced treatment protocols.
  • Requires specialized molecular testing for accurate diagnosis and management.

5. Hormone Receptor-Positive Breast Cancer


  • Hormone Receptor-Positive Breast Cancer cells containing estrogen or progesterone receptors.
  • Grows in response to hormonal stimulation.
  • Potentially treatable with hormone-blocking medications and targeted therapies.

Major Risk Factors


Genetic Predisposition


  • Inherited BRCA1 and BRCA2 gene mutations significantly increase breast cancer likelihood.
  • Family history of breast or ovarian cancer raises personal risk profile.
  • Genetic testing helps identify potential inherited cancer susceptibilities.

Age-Related Risks


  • Breast cancer risk increases substantially after age 40.
  • Hormonal changes during menopause contribute to potential cancer development.
  • Regular screenings become increasingly important with age progression.

Lifestyle and Environmental Factors


  • Obesity and sedentary lifestyle increase potential breast cancer risks.
  • Alcohol consumption and smoking impact overall cancer susceptibility.
  • Prolonged hormonal contraceptive use may influence cancer development potential.

Reproductive History


  • Late pregnancy or no childbirth increases breast cancer risk.
  • Early menstruation and late menopause extend hormonal exposure.
  • Hormonal fluctuations contribute to potential cancer development.

Screening Recommendations


  • Annual mammograms after age 40
  • Regular clinical breast examinations
  • Genetic testing for high-risk individuals
  • Monthly self-examinations
