What Are The Types Of Skin Cancer On Feet
Basal Cell Carcinoma : Frequently seen on sun-exposed skin and typically results from excessive Ultraviolet radiation exposure from sunlight or sunbed use. It does not usually spread beyond the skin and it is one of the least aggressive cancers. This may appear as a pearly/white bump/patches that may ooze or crust and have an appearance of an open sore.
Squamous Cell Carcinoma : The most common form of cancer of the feet. This is usually confined to the skin and does not spread. However, when advanced it can become more aggressive and spread throughout the body. This form of cancer often begins as a small, scale-like bump that may crack or bleed. Sometimes it may be inflamed. It can be painless, but sometimes itchy and can have a hard projecting callus-like lesion.
Malignant Melanoma: One of the deadliest forms of skin cancers and the key to survival is early detection. This can appear on any areas of the foot, including under toenails. They are commonly found on both the soles and the top of the feet. As this cancer grows it extends deeper into the skin.
This kind of cancer is nicknamed, The Great Masquerader as it has many appearances. Melanoma commonly begins as a small brown-black spot or bump. It will appear to have an asymmetry, irregular borders, alterations in colour and a diameter greater than 6mm.
Check Every Part Of Your Feet For Signs Of Melanoma
Pay close attention to places on your feet that have been injured. Even if the injury was years ago, examine the area carefully.
Research has shown that a foot injury may increase your risk of developing melanoma. Bob Marley, a legendary reggae artist, developed melanoma on his foot. Its believed that the melanoma began where he had injured his foot while playing soccer. He later died of melanoma.
Signs And Symptoms Of Cancer
Signs and symptoms are ways the body lets you know that you have an injury, illness, or disease.
- A sign, such as fever or bleeding, can be seen or measured by someone else.
- A symptom, such as pain or fatigue, is felt or noticed by the person who has it.
Signs and symptoms of cancer depend on where the cancer is, how big it is, and how much it affects nearby organs or tissues. If a cancer has spread , signs or symptoms may appear in different parts of the body.

Treatment Options For A Bone Tumor Of The Foot
Some benign bone tumors of the foot may not require treatment. For instance, a benign bone tumor that occurs in a child may resolve over time.
Monitoring of the tumor may be all that is needed. Some people with bone tumors can be treated effectively with medication. Others, such as those with osteochondroma, may require surgery. Excision of the tumor often solves the problem, although bone tumors can recur.
For people with malignant bone tumors, treatment may involve several specialists and a combination of interventions, including radiation therapy, chemotherapy, and surgery. The surgeon will need to take out the tumor and some of the healthy tissue and bone around it.
In some instances, the excised bone can be replaced with a metallic implant or bone transplant . In cases of advanced bone cancer, amputation of the foot may be necessary.
After you have been treated for a bone tumor, you will have to return for follow-up and undergo more radiographic testing so your doctor can make sure that the treatment was successful and that the tumor has not recurred.

Treatment Of Foot Cancer
The treatments available for foot melanoma depend on the stage the cancer has reached and your overall state of health. If caught early enough , the mole and surrounding skin may simply be removed however, the anatomy of the foot is extremely complex, making surgery difficult if the cancer has penetrated the tissues.
For more advanced cancer, the treatment options are chemotherapy with cytotoxic drugs, immunotherapy that stimulates the immune system to attack the cancer cells, radiation therapy, or an operation called a lymphadenectomy that removes the surrounding lymph nodes. Bone cancers in the foot are typically resolved by removing the affected bone, treatment via chemotherapy and radiation therapy.

Is Bone Cancer Usually Fatal
Not usually. Though some people will die of bone cancer, many others will make a full recovery. The five-year relative survival rate for bone cancer is 66.8%. This means that 66.8% of people with bone cancer are still alive five years after their diagnosis. Keep in mind that survival rates are only estimates based on people whove had bone cancer in the past. They cant predict how long you will live or what to expect in your unique situation.

What Is Bone Cancer
Bone cancer is the term for several different cancers that develop in the bones. When cancer cells grow in a bone, it can harm normal bone tissue. The type of cell and tissue where cancer begins determines the type of bone cancer.
Cancers that form in the bone itself are called primary bone cancers. Many tumors that begin in organs or other parts of the body can spread to the bones, as well as other body parts. These growths are called secondary or metastatic bone cancers. Breast, prostate and lung tumors most commonly metastasize to the bones.
How Bone Cancer Is Treated
Treatment for bone cancer depends on the type of bone cancer you have and how far it has spread.
Most people have a combination of:
- surgery to remove the section of cancerous bone it’s often possible to reconstruct or replace the bone that’s been removed, but amputation is sometimes necessary
- chemotherapy treatment with powerful cancer-killing medicine
- radiotherapy where radiation is used to destroy cancerous cells
In some cases of osteosarcoma, a medicine called mifamurtide may also be recommended.

How Is Bone Cancer Treated
Bone cancer treatment depends on the type of cancer, whether it has spread and if so, where. People with bone cancer often work with a team of healthcare providers to treat the condition. This group includes doctors who specialize in cancer and doctors who specialize in bones and joints .
Bone cancer treatment typically involves a combination of approaches. The type and duration of these treatments vary depending on several factors, including the type of bone cancer, the size of the tumor and whether it has spread to other parts of the body. The treatments most commonly used include:
- Surgery: Your surgeon removes the tumor and some healthy tissue around it. They can also repair or rebuild affected bones with real or artificial bone grafts. Sometimes, an entire limb must be removed to treat cancer. In this case, an artificial limb can be used. Sometimes repeat surgery is needed if all of the cancer cells were not removed the first time around.
- Radiation therapy: This treatment shrinks the tumors with high doses of X-rays. Healthcare providers often use radiation before surgery to shrink the tumor so less tissue has to be removed.
- Chemotherapy: This type of treatment kills cancer cells throughout the body with medicine. People usually receive this medicine by swallowing a pill or having it injected into a vein. Your provider can use chemotherapy to treat primary bone cancers or bone cancers that have spread.

Types Of Cancer Affecting The Feet
Skin cancer is the most common type of cancer found on the feet. Some of the most common types include:
- Basil cell carcinoma. Basal cell carcinoma is a nonaggressive type of skin cancer that is typically caused by sun exposure. It generally stays in one spot on the foot and does not spread to other areas. It is characterized by white-colored bumps that often are scaly or seeping fluid and typically occurs on the tops of the feet.
- Malignant melanoma. Malignant melanoma is the most aggressive form of skin cancer. It can occur on the tops or bottoms of the feet, or under the toenails. It is characterized by a mole-like appearance that is either black, pink, or red. The mole may have irregular edges and look jagged. This type of cancer can spread to other areas such as the lymph nodes if not treated in its earliest stages.
- Squamous cell carcinoma. The most common type of foot cancer is squamous cell carcinoma. This type of skin cancer may first appear as a small rough patch or bump on the foot. It can also appear as an open sore. It does not typically cause pain, but can crack, bleed, or become itchy. Squamous cell carcinoma can spread to other parts of the body if left untreated.
Not all tumors are cancerous. There are benign tumors that can develop in the feet. These can occur on the bones, nerves, and tissues of the feet. Some benign tumors do not require treatment while others may need to be removed.
Signs And Symptoms Of Bone Cancer
There are different types of primary bone cancer. Signs and symptoms depend mainly on the type, location, and extent of the cancer.

Chondrosarcoma: This tumor may occur in adults between 40 and 70 years of age. It more commonly develops in the pelvis, femur, or shoulder. When chondrosarcoma develops in the foot, it can be difficult to distinguish from an enchondroma.
Ewings sarcoma: Children and adults up to 20 years of age may have Ewings sarcoma. The tumor may be present for many months before it becomes large enough to cause pain and swelling. The chances of survival are better for those who have a bone tumor of the forefoot than those with a bone tumor of the hindfoot.
Osteosarcoma: Osteosarcomas of the foot can easily be misdiagnosed, especially because they almost always occur in adults, whereas most cases of osteosarcoma in other parts of the body occur in teenagers.
