cancerous and able to spread
Describes a cancer or tumor that is dangerous because it grows quickly and can spread to other parts of the body.
用法模式：
malignant [tumor/cancer/growth/cell]
常见错误：
Learners often confuse 'malignant' with 'benign'. 'Malignant' means the tumor is dangerous and can spread, while 'benign' means it is not cancerous and usually not life-threatening. Another mistake is using 'malignant' before people in a medical context; in medicine, it typically describes tumors, cells, or diseases, not patients.
近义词
cancerous (More general medical term; focuses on the presence of cancer, while 'malignant' highlights the dangerous, invasive nature.)
反义词
benign (Used for tumors or growths that are not cancerous and do not spread, so they are usually much less dangerous.)

Very bad and cruel, with a strong wish to hurt or damage people.
用法模式：
malignant [attitude/hatred/influence/character]
常见错误：
Learners sometimes assume 'malignant' can be used for any kind of 'bad' thing, like 'a malignant test' or 'a malignant day'. It is normally used for very serious evil or harm, especially for people’s character, intentions, or powerful harmful forces. Also, 'malignant' is stronger and more formal than simply 'mean' or 'bad'.
近义词
malevolent (Very close in meaning; slightly more formal and often used in literary or descriptive contexts.)
反义词
benevolent (Describes someone who wants to do good and help others, the opposite of a malignant, harmful nature.)

very severe, life-threatening disease
Describes a very serious illness that gets worse quickly and can cause death if doctors do not treat it fast.
用法模式：
malignant [condition/disease/hypertension]
常见错误：
Learners may think 'malignant' in medical texts always means 'cancer', but it can also describe other very severe, fast-worsening conditions, such as 'malignant hypertension'. In these cases it means extremely serious and life-threatening, not necessarily cancer.
近义词
life-threatening (A more general, less technical term meaning that a condition could cause death.)
反义词
mild (Describes a disease or condition that is not serious and does not usually cause severe harm.)
