Lobular carcinoma in situ. This lesion is often encountered as a microscopic lesion that does not form a palpable tumour. It is generally regarded as a risk indicator rather than a direct precursor for subsequent invasive breast cancer development in both ipsilateral and contralateral breasts.
lobular carcinoma in situ. a very early type of breast cancer that develops within the milk-producing glands (lobules) of the breast and does not penetrate through the wall of the lobules. Researchers think that lobular carcinoma in situ cells almost never progress to invasive lobular cancer. However, having this type of cancer places a woman at increased risk of developing an invasive breast cancer later in life which can occur in either breast. For this reason, it's important for women with lobular carcinoma in situ to have a physical examination three times a year and an annual mammogram.
Lobular carcinoma in situ. It is a misnomer which describes a benign proliferative process in the lobular units. It does not have specific mammographic features and is usually detected by chance in the course of a breast biopsy for another lesion.
