Sarcoma Symptoms: Swelling, Lumps and More

Sarcomas are rare, and they make up less than 1% of cancers. Sarcomas can happen anywhere in your body. How do you identify sarcoma symptoms? The list below may help you determine if you should see a doctor.

What is a Sarcoma?

Cancer is the uncontrolled growth of abnormal cells, and cancerous tumors of the connective tissues are called sarcomas.

These tissues connect, support and surround other body structures, so there are many types of tissue with many different jobs around the body.

Normal connective tissue includes:

  • Fat.
  • Blood vessels.
  • Nerves.
  • Bones.
  • Muscles.
  • Deep skin tissues.
  • Cartilage.

They are two types of sarcoma: bone sarcomas and soft tissue sarcomas. These all share microscopic similarities and have similar symptoms.

Sarcoma Symptoms to Watch For

Here are the seven most common sarcoma symptoms:

1. A Lump or Mass

This is the most common symptom of sarcomas. A noticeable lump forms in the location where the tumor is growing.

A typical mass grows slowly over a period of time and is often painless in the beginning. Over time, or if the lump presses on a nerve or muscle, it will start to ache. If the lump isn’t painful but continues to grow or if it is located deep within an extremity or body cavity, see a doctor.

Many of these lumps are not sarcoma; in most instances, these soft-tissue lumps are made of fat cells and are not cancer. If you have a lump that is larger than 2 inches, growing or painful, it should be brought to the attention of your doctor.

2. Localized Pain

Once a tumor affects the tissues, pain can be felt in the general area. As the cancer develops, the ache will become more persistent. If the tumor presses against nerves and muscles, it will make the pain more pronounced.

Soft tissue sarcomas can develop in flexible tissues and rarely cause symptoms in the early stages. The tumor pushes normal tissue out of the way while it grows, so it can become quite large before symptoms are noticeable. Location-specific pain can result depending on the location of the sarcoma. A sarcoma in the heart will cause chest pain, in the lungs it will cause breathing issues and in the abdomen it can cause digestion issues.

Bone sarcomas will be paired with bone pain. A dull or deep ache is felt in a bone or bone region. At first, the pain may only be noticeable at night or in periods of inactivity. These pain points are usually where the bone has weakened, which can lead to a fracture down the road. The break may occur in an area of bone that was previously painful for a period of time, so be sure to let your doctor know of any areas that hurt so they can monitor the state of the area.

3. Swelling

Uncomfortable swelling, especially in the limbs that have tumors, is another sign of soft tissue sarcoma. Tumors in or around the joints often cause swelling and tenderness.

While you may notice that your arm or leg is swelling due to the tumor, you may not feel any pain. This inflammation is the result of the tumor growing and swelling. Over time, the site may become increasingly tender, so it is best to see a doctor when you first notice swelling.

4. Limited Mobility

Some tumors restrict motion like in the hip, knee, shoulders or hands. Location-specific symptoms can mean that you walk with a limp, lack a full range of motion or are unable to move your limbs properly.

The tumor may cause the impairment of a joint, muscle, or another type of tissue, or the pain may be so great that you are unable to maneuver your body as you did before the sarcoma appeared. Sometimes this symptom is confused with a sports injury.

5. Skin Lesions

Spots appear when a sarcoma tumor breaks through the skin and are red, brown or purple in color. Usually, these lesions are not itchy or painful. They can be flat on the skin, slightly raised from the surrounding skin, or grow into small nodules (bumps).

The lesions can appear all over and inside the body, including the mouth, inside the lungs, or within the stomach and intestines. The location of the lesions offers their own additional side effects, including abdominal pain, bleeding, diarrhea and more. In some cases, lesions bleed, and prolonged bleeding can result in a lower red blood cell count, leading to anemia.

6. Weight Loss

With cancer, weight loss is a common symptom. Unintended weight loss can be the result of a few things relating to sarcoma.

It is possible to feel full after eating a small amount of food. You may also be skipping meals because of a lack of appetite. Your body may not be absorbing the nutrients it needs, as stomach pain or vomiting may be a barricade to keeping your weight up.

With advanced sarcoma, you may experience muscle loss as well.

7. Fatigue

Cancer causes fatigue through mental, physical and emotional depletion. The constant pain, improper sleep, poor nutrition and lack of essential nutrients all add to the effect of fatigue.

Managing sarcoma symptoms also contributes to drowsiness and fatigue, with the toll medication and treatment takes on the body.

In Conclusion

Depending on where the sarcoma is located in the body, it will determine which symptoms present. Your doctor will determine the next steps and help you come up with a treatment plan and long-term care.
