(1) the degree of differentiation: benign tumor differentiation is good, atypia is small, and the original organization has a similar form; malignant tumor differentiation is not good, atypia, and the original tissue morphology difference.
(2) mitotic like: benign tumor mitotic like no or rare, no pathological mitotic like; malignant tumor mitotic like more common, and visible pathological mitotic image.(3) growth rate: benign tumor slow; malignant tumor faster.
(4) growth mode: benign tumor more common swelling and exogenous growth, the former often capsule formation, and the surrounding tissue in general clear boundaries, it is usually able to promote; malignant tumors for invasive and exogenous growth, the former without capsule Formation, and the surrounding organization is generally unclear boundaries, it is usually not to promote, which is accompanied by invasive growth.
(5) secondary changes: benign tumors rarely necrosis and bleeding; malignant tumors often necrosis, bleeding and ulceration.
(6) metastasis: benign tumors do not transfer; malignant tumors often transfer.
(7) relapse: benign tumor surgery rarely relapse; malignant tumor surgery and other recurrence after treatment.
(8) on the body: benign tumor is small, mainly caused by local oppression or obstruction, such as occurs in important organs can also cause serious consequences; malignant tumors, in addition to oppression, obstruction, but also can destroy the primary and metastatic Of the organization, causing necrosis bleeding combined with infection, and even cause cachexia.
In fact, benign tumors and malignant tumors sometimes there is no absolute boundaries, more understanding of some of the treatment is very helpful.
