Lumpectomy vs. Tylectomy — Which is Correct Spelling?

Lumpectomy (sometimes known as a tylectomy, partial mastectomy, breast segmental resection or breast wide local excision) is a surgical removal of a discrete portion or "lump" of breast tissue, usually in the treatment of a malignant tumor or breast cancer. It is considered a viable breast conservation therapy, as the amount of tissue removed is limited compared to a full-breast mastectomy, and thus may have physical and emotional advantages over more disfiguring treatment.

Surgical excision of a tumor from the breast with the removal of a minimal amount of surrounding tissue. Also called tylectomy.

Surgical excision of a mass.

(surgery) The surgical removal of a tumour or cyst from a breast.

The removal of a cyst or tumor from the breast by surgery. This is one method of treating breast tumors when in an early stage, and is preferred for cosmetic reasons, when medically feasible, to radical mastectomy, the removal of the entire breast along with nearby muscles.

Surgical removal of a tumor without removing much of the surrounding tissue or lymph nodes; performed in some cases of breast cancer
