Dysplasia in high degree is a pre-neoplasic state; not in moderate or mild degree. Neoplasia is a true tumoral situation

Epithelial Dysplasia is the anapasia of epithelium which can be Mild ,moderate or severe.MalignantNeoplasia is tumoural condition wherein dysplastic epithelium breaches the basement membrane and invade the underlying connective tissue stroma.

Dysplasia is a cellular change which occurs to develope neoplasm

Thank you very much dear doctors for answering my question,really great thanks.

Dysplasia is a pre neoplastic condition; neoplasia is a jet tumor

Dysplasia is the early changes in cells  can not be called  tumour, while neoplasia is tumoral.

Dysplasia (disorderly differentiation) is the collection of microscopically recognizable changes in the epithelium which increases risk of cancer formation. Dysplasia applies to only epithelium and the changes are @ tissue level.

Individual changes @ cellular level is called anaplasia.

Neoplasia is tumor per se & can occur @ any tissue including epithelium.

I fully agree with all the comments suggested my collleagues

Dysplasia is a tissue condition which may or may not transform to malignancy.eg mild cervical dysplasia does not form to malignancy.

There is a great difference between both. Dysplasia is a benign lesion and can be neoplastic in the future

but is there gwnetic change in dysplasia?

Dysplasia is pre-neoplasic lesion with 3 categories mild, moderate and severe. Two of them are previous and the third is very close to neoplasia

Dysplastic changes are reversible but Neoplastic changes are irreversible.

Dysplastic changes are polycolonal while Neoplastic changes are monoclonal.

Is the previous stage of a neoplasia but takes a long time before the change of a true neoplasia
