Methods to diagnose bone cancer – Biopsy
A biopsy is a medical procedure that removes a tissue sample for microscopic examination. The biopsy is the most conclusive test because it confirms if the tumor is malignant or benign, the bone cancer type (primary or secondary bone cancer), and stage.
Types of biopsy procedures used to diagnose bone cancer include:
Needle Biopsy
During a needle biopsy, the surgeon makes a small hole in the bone and removes a sample of tissue from the tumor with a needle-like instrument. There are 2 types of needle biopsies: fine needle biopsies and core needle biopsies. In Fine Needle Biopsy, the tissue sample is removed with a thin needle attached to a syringe. In Core Needle Biopsy, the doctor removes a small cylinder of tissue sample from the tumor with a rotating knife like device.
Surgical bone biopsy
In this procedure, a surgeon needs to cut through the skin to reach the tumor in order to remove a small piece of tissue. This is also called an incisional biopsy. If the entire tumor is removed (not just a small piece), it is called an excisional biopsy. These biopsies are often done under general anesthesia (with the patient asleep). They can also be done using a nerve block, which makes a large area numb.

Diagnosis of Cervical Cancer
Doctors recommend that women help reduce their risk of cervical cancer by having regular Pap tests. A Pap test is a simple test used to look at cervical cells. Pap tests can find cervical cancer or abnormal cells that can lead to cervical cancer. To perform a Pap test, a health professional uses a spatula, brush, or cotton swab to collect cells from the cervix The narrow, lower end of the uterus (womb). and cervical canal. The cells are then “smeared” on a slide, preserved with a fixative, stained, and sent to a laboratory for microscopic analysis by a cytopathologist.
If the Pap test results show some problems, then your doctor will perform these tests :
Cone Biopsy
A cone-shaped piece of tissue is removed. The cone biopsy is also a treatment, and can completely remove many precancers and early cancers. More than 90 percent of cervical cancers can be halted with this technique without further treatment. Tissue is removed from the area between the ectocervix and the endocervix. It includes two methods :
- LEEP : A loop electro surgical excision procedure (LEEP) is a procedure done under local anesthesia to remove tissue from the cervix. A LEEP uses an electrically charged wire loop to remove a tissue sample.
- Cold knife cone biopsy : The physician uses a surgical scalpel or laser (intense, focused light beam) to remove abnormal cervical tissue. It is done under general anesthesia.
Colposcopy
The colposcope combines a bright light with a magnifying lens to make tissue easier to see. It is not inserted into the vagina. A colposcopy is usually done in the doctor’s office or clinic. If colposcopy reveals abnormal areas on the cervix, the physician will order a biopsy.
Endocervical Curretage
After the anasthesia is given, a narrow instrument called a curette is inserted into the endocervix and cells are taken.
Dilation And Curettage (D&C)
During a “D&C,” the physician enlarges the cervix (dilation) and scrapes the inside of the uterus and cervical canal (curettage) to remove tissue for microscopic analysis.
Cervicography
It examines a photographic image of the cervix. Cervicography may clarify abnormal Pap test results in women.
