No, that's the opposite, most malignant cells have lost their ability to undergo apoptosis.

Malignant cells in general?
Malignant cells are cell that are not in use at the current time.
What might happen if apoptosis did not occur in cells that have significant DNA damage?
Most likely cancer would arise if apoptosis did not occur in cells that have significant DNA damage.
How do human cells die?
by apoptosis and necrosis
Contrast apoptosis and cancer?
Cancer is the uncontrolled growth and division of cells. Apoptosis is a programmed cell death.
What is Apoptosis and what role does it play?
Apoptosis is when cells destroy themselves. This is done for two main reasons:To destroy cells which are a risk to the organism, such as cells with viruses.It is important in normal development, such as shedding the lining of the uterus (menstruation).
How have Malignant cells changed?
Malignant cells have changed such that they lose normal control mechanisms governing growth
A malignant tumor is a mass of cells that?
A malignant tumor is a mass of cells that invades and distroys healthy tissue.
What does negative malignant cells mean?
A malignant cell is a cancer cell. Once that is growing out of control. No malignant cell means the absence of cancer cells. This means the observed cells are healthy.
Ki67 is in 40 percent of the cells?
malignant cells
How apoptosis can prevent abnormal cells from becoming tumors?
Apoptosis might be seen as part of the body's overseeing/managing/protecting mechanism. Apoptosis is associated with cell death; a programmed cell death, where "abnormal" cells, which either cannot function properly (aged, injured, etc), or are potential threat to the organism (infected, mutated), have to die. By activating apoptosis of those cells, the body stops their proliferation. If this mechanism gets impaired (for example tumour suppressor genes, like p53, cannot promote apoptosis), the uncontrolled proliferation of the abnormal cells could lead to malignancy.

Why dont cancer cells undergo apoptosis?
In cancerous cells, the normal programming to undergo apoptosis may not be activated due to the nonreception of proapoptotic signals, the decrease or lack of synthesis of proapoptotic signals, the increase in the synthesis of antiapoptotic signals, or a combination of all of these.
