30. Investigations
Ultrasonography Mammography

31. • Fine needle aspiration
• Obtain cells for microscopic
examination
• Less reliable
• Biopsy
• Obtain tissue sample for
microscopic examination
• “...diagnosed upon the basis of a
microscopic examination of the
fixed tissue, supported by a biopsy
result.”

32. • CT scan
• To assess distant spread

33. Treatment options
• Surgery
• Chemotherapy
• Radiotherapy
• Hormonal therapy
• Targeted therapy

34. Breast surgery
Mastectomy Lumpectomy/Breast-conserving surgery

35. Quadrantectomy

36. Axillary (armpit) surgery
Axillary dissection Sentinel lymph node biopsy

37. Treatment options
• Surgery
• Chemotherapy
• Radiotherapy
• Hormonal therapy
• Targeted therapy

38. Survival

39. Conclusion
• Breast cancer is very common
• Early detection saves lives
• Various modalities available for early detection
• Everyone associated with healthcare has a role to play to reduce its
incidence
