Can a tumor be long and skinny?

Dermatofibrosarcoma protuberans, also called DFSP, is a slow growing tumor consisting of long, narrow cells with tapered ends. Because of their appearance, doctors call them spindle cells. These tumors form in the skin or just below it, and surgery can lead to a remission.

Can tumors be elongated?

Soft tissue tumors can be cancerous or benign. Benign masses are thought to occur 10 times more frequently than cancerous growths (referred to medically as sarcomas). Generally these growths are roughly round in shape, but they also can be or elliptical or elongated like a sausage.

What does a sarcoma look like?

Soft-tissue sarcoma usually looks like a rounded mass beneath the skin surface. The skin is usually unaffected. The mass may be soft or firm. If the mass is deep, the arm or leg may appear larger or fuller than the other side.

Is cancer/tumor hard or soft?

Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months. Cancerous lumps that can be felt from the outside of your body can appear in the breast, testicle, or neck, but also in the arms and legs.

How do I know if my lump is sarcoma?

A sarcoma may appear as a painless lump under the skin, often on an arm or a leg. Sarcomas that begin in the abdomen may not cause signs or symptoms until they get very big. As the sarcoma grows bigger and presses on nearby organs, nerves, muscles, or blood vessels, signs and symptoms may include: Pain.

Are tumors smooth or rough?

They usually feel smooth and may roll under the skin when pressure is applied to them. If you look closely, you will see a small opening to the surface, called an epidermal pore. Skin tumors are abnormal growths of tissue that can be malignant (cancerous) or benign (harmless).

Are Cancerous tumors symmetrical?

In cancer, cell division is often an asymmetric process that can be thought of as a series of symmetry breaking events. When occurring over many cell divisions a population of cancer cells displays tumor heterogeneity where a high number of cells have slightly different genetic and phenotypic states.

When should you suspect sarcoma?

In particular, we recommend all lumps >4cm should be investigated to obtain a diagnosis, and anyone with bone pain and reduced function of the limb or with night pain should be investigated for a bone sarcoma.

Are sarcomas soft or firm?

Soft tissue sarcomas can be big or small, hard or soft, quick or slow growing. They are usually not painful until they become large enough to press on organs, nerves, muscles or blood vessels. Symptoms will vary based on the location of the sarcoma.

How long can you have sarcoma without knowing?

It would appear that some people are quite happy to live with asymptomatic lumps for up to 5 or more years and our experience shows that most of these patients will have been re-assured by one or more doctors during this time. A long duration of symptoms has been shown to correlate weakly with good prognosis.

How do you tell if a lump is a tumor?

If the lump has solid components, due to tissue rather than liquid or air, it could be either benign or malignant. However, the only way to confirm whether a cyst or tumor is cancerous is to have it biopsied by your doctor. This involves surgically removing some or all of the lump.

Do tumors hurt when you press on them?

Compression. As a tumor grows it can compress adjacent nerves and organs, resulting in pain. If a tumor spreads to the spine, it can cause pain by pressing on the nerves of the spinal cord (spinal cord compression).

How does a tumor feel?

The way a tumor feels depends on its size, location, type, stage, and other factors. A cancerous lump in the breast, for example, tends to feel firm or solid and might be fixed to underlying tissue. Such lumps are often painless but do produce pain in a small percentage of patients.
