Does cancerous tissue look different?

Size and shape of the cells

The overall size and shape of cancer cells are often abnormal. They may be either smaller or larger than normal cells. Normal cells often have certain shapes that help them do their jobs. Cancer cells usually do not function in a useful way and their shapes are often distorted.

What color is cancerous breast tissue?

Dense (fibrous and glandular) breast tissue looks white on a mammogram. Breast masses and cancers can also look white, so the dense tissue can make it harder to see them. In contrast, fatty tissue looks almost black on a mammogram, so it's easier to see a tumor that looks white if most of the breast is fat tissue.

A breast cancer lump often feels like a pea- or marble-shaped mass just under the skin.

What are some characteristics of cancerous tissue?

What do precancer cells look like?

Discoloration, often appearing brown, pink, gray, red, yellow, or white. Flat or slightly raised. Hard or wart-like surface.

What type of tissue are most cancers found?

Carcinomas, malignancies of epithelial tissue, account for 80 to 90 percent of all cancer cases. Epithelial tissue is found throughout the body. It is present in the skin, as well as the covering and lining of organs and internal passageways, such as the gastrointestinal tract.

Does cancerous tissue hurt?

Often, cancer does not cause pain, so do not wait to feel pain before seeing a doctor.

What is pre cancerous tissue?

Precancer simply means there are cells that have grown abnormally, causing their size, shape or appearance to look different than normal cells. Whether abnormal cells become cancerous is, in many cases, uncertain.

Is cancerous tissue painful?

As the tumor grows, it may cause: A noticeable lump or swelling. Pain, if a tumor presses on nerves or muscles.

When should I be concerned about breast tissue?

Breast Changes of Concern

Check with your health care provider if your breast looks or feels different, or if you notice one of these symptoms: Lump or firm feeling in your breast or under your arm. Lumps come in different shapes and sizes. Normal breast tissue can sometimes feel lumpy.

Can you tell if a breast lump is benign without a biopsy?

A healthcare provider may use imaging tests such as mammograms, ultrasound, and magnetic resonance imaging (MRI) to help make a diagnosis. Still, the only way to know for sure is to have a biopsy of the tissue at the lump site.

Can you tell if a mass is cancerous without a biopsy?

Imaging tests, such as CT scans or MRIs, are helpful in detecting masses or irregular tissue, but they alone can't tell the difference between cancerous cells and cells that aren't cancerous. For most cancers, the only way to make a diagnosis is to perform a biopsy to collect cells for closer examination.

Can you tell if a tumor is benign without a biopsy?

There is no way to tell from symptoms alone if a tumor is benign or malignant. Often an MRI scan can reveal the tumor type, but in many cases, a biopsy is required.

What happens if a biopsy is positive?

Generally, after a patient receives positive melanoma results, his or her doctors will need to proceed with staging the malignancy— which essentially means determining the extent of the cancer—and developing a treatment plan based on how far the cancer has progressed.
