**Core Concept**
A cervical cone biopsy is a diagnostic procedure used to obtain a tissue sample from the cervix, which can be affected by various conditions, including cervical cancer. The procedure involves removing a cone-shaped sample of tissue from the cervix, which can lead to several complications.

**Why the Correct Answer is Right**
The correct answer is that a cervical cone biopsy does not cause the spread of malignancy. This is because the procedure is a diagnostic tool, not a therapeutic one. The aim of the biopsy is to obtain a tissue sample to determine the presence and extent of cancer. The procedure itself does not involve the use of any instruments that could potentially spread cancer cells. However, it's essential to note that the procedure can cause other complications, such as bleeding, infection, and cervical stenosis, due to the manipulation of the cervix and the removal of tissue.

**Why Each Wrong Option is Incorrect**
**Option A:** Bleeding is a possible complication of a cervical cone biopsy, especially if the procedure is performed too aggressively or if the patient has a bleeding disorder. However, it is not the only complication, and the question asks for an exception.

**Option B:** Cervical stenosis is a possible long-term complication of a cervical cone biopsy, especially if the procedure is performed multiple times or if the patient has a pre-existing condition that affects the cervix.

**Option C:** Infection is a possible complication of a cervical cone biopsy, especially if the procedure is performed in a setting where proper sterile techniques are not followed.

**Option D:** Spread of malignancy is not a known complication of a cervical cone biopsy. The procedure is designed to obtain a tissue sample to diagnose cancer, not to spread it.

**Clinical Pearl / High-Yield Fact**
It's essential to note that cervical cone biopsies should be performed by experienced healthcare providers in a sterile environment to minimize the risk of complications.

**✓ Correct Answer: D. Spread of malignancy**
