What does it mean to have a poorly differentiated cancer?

Hypo-differentiated carcinoma is clinically defined as a group of malignant tumors that are less differentiated, more malignant and have a poorer prognosis.
Hypo-differentiated carcinoma belongs to a special term for pathological diagnosis, which is generally a malignant tumor of epithelial tissue origin. Tumor cells have a low degree of differentiation and differ greatly in structure, morphology and size from normal cells in the area, which makes poorly differentiated carcinoma highly malignant, not easy to be treated, with poor prognosis, easy to recur and low survival rate.
Low-differentiated cancer is often treated with surgery, plus some auxiliary chemotherapy, radiotherapy or targeted therapy. Generally speaking, the 5-year survival rate of poorly differentiated cancer is relatively low, so early detection, early diagnosis and early treatment are necessary.
