Multistep model of cancer development
WebCytogenetic and molecular genetic analysis of breast cancer samples demonstrates that tumour development involves the accumulation of various genetic alterations including amplification of oncogenes and mutation or loss of tumour suppressor genes. WebMultistep carcinogenesis of breast cancer and tumour heterogeneity Breast cancer emerges by a multistep process which can be broadly equated to transformation of normal cells via the steps of hyperplasia, premalignant change and in situ carcinoma.
