  • Good Afternoon, Good Evening and Good Morning to all Participants in today’s e-grandround.I would like to thank European School of Oncology for allowing me to make this presentation.I would also like to thank Dr. Fatima Cardoso who is my Discussant for this session.And my greetings to FracescaMarangoni of the ESO. I will now start my presentation on Lifestyle Modification and prevention of Breast Cancer. (Slide 4 please)
  • In order to discuss Lifestyle modification and prevention of breast cancer and to identify the factors which may influence the development of Breast Cancer we will remind ourselves of the steps that are likely to lead to breast cancer.The cells in the breast ducts and Lobules undergo Cell Proliferation under the influence of oestrogen Hormone.When breast cells are maturing particularly rapidly between Menarche and First Live Birth, they are most likely to be affected by cancer causing agents. (Slide 5 Please).
  • After the first Live birth Breast cells have matured and are less sensitive to such stimuli.Breast feeding further reduces the breast cell sensitivity to mutations. (Slide 6 please)
  • Normal ductal cells are in single layerWhen these cells proliferate too much they can become abnormal. (Slide 7 please)
  • Proliferating breast cells can change shape and orientation and thus become Dysplastic. (Slide 8 please)
  • Ovarian Oestrogen and Prgesterone affects breast stimulating the oestrogen ReceptorsDietary oestrogen and body fat affects breast via peripheral conversion requiring the enzyme Aromatase. (Slide 9 please)
  • All these factors have made the breast cancer as the commonest cancer in women. (Slide 10 please)
  • …. Slide 11 please
  • Although breast cancer is the commonest cancer diagnosed in women it has good treatments available and Breast Cancer is not the commonest cause of death in females. (Slide 12 please)
  • The incidence of breast cancer has been rising for many years but its mortality is falling primarily because of The increasing use of chemotherapy in pre menopausal women, RT after breast conserving surgery, the use of Tamoxifen and more recently Herceptin.The results of these improvements are an Increased number of SURVIVORS. (Slide 13 please)
  • When we look at the age of patients who have had operative treatment for a potentially curable breast cancer we notice that there are very few patients under the age of 30 who are diagnosed with breast cancer. Does it mean that something at the age 0f 30 makes them develop breast cancer? It is more likely that the agents responsible for breast cancer have been working since the birth and have taken a number of years to produce breast cancer. Lifestyle modification therefore need to start right from the birth of a female child. (Slide 14 please)
  • When we look at this slide we will notice that there can been be many different types of breast cancer. (Slide 15 please)
  • Their radiological appearance s are different. (Slide 16 please)
  • Their clinical presentations are different (Slide 17 Please)
  • The life events that are associated with breast cancer are well recognized (Slide 18 Please)
  • It is more likely that in patients who develops breast cancer many of these are working in combination at different time in their life. (Slide 19 please)
  • Histologically we know that there are two main types of breast cancer, Ductal and Lobular (Slide 20 Please)
  • Slide 21 please
  • A 50 years old lady who is pre menopausal has a higher risk of breast cancer than a fifty years old who has achieved menopause.Reduction in body weight around menopause decreases the risk of breast cancer. (Slide 23 Please)
  • The three main lifestyle changes that can reduce the risk of breast cancer are Diet, Having children below the age of 30, Multiparity and reduction in the amount of alcohol consumtion. (Slide 25 please)
  • Footballers wife has a child at 23 where as a lady who has three degrees has her first child at 35. This is a modifiable lifestyle factor. (Slide 30 Please)
  • Practical approaches to dietary modification that include increasing fruit and vegetable consumption, eating a low fat diet, reducing meat consumption, and avoiding alcohol are likely to be of potential overall benefit in lowering the risk of breast cancer.Three types of my patients ask about Lifestyle modification for the prevention of breast cancer 1. those who have had treatment for breast cancer2. Patients who have had breast cancer and have survivors ask about their daughters. Third who have some form of breast cancer in the family.
