Can chronic wounds cause cancer?
Wounds could allow certain types of mutated cell to migrate to the surface of the skin, triggering tumours in people predisposed to cancer, according to a study.
Malignant or fungating wounds occur when cancerous cells invade the epithelium, infiltrate the supporting blood and lymph vessels, and penetrate the epidermis. This results in a loss of vascularity and therefore nourishment to the skin, leading to tissue death and necrosis.
Signs and symptoms of an ulcerating cancer wound
leakage or discharge. an unpleasant smell. pain. bleeding.
Basal cell cancers are often fragile and might bleed after shaving or after a minor injury. Sometimes people go to the doctor because they have a sore or a cut from shaving that just won't heal, which turns out to be a basal cell cancer.
New research reveals that even a minor flesh wound can cause previously dormant cancer cells to develop into tumors. The study, published in the Proceedings of the National Academy of Sciences, focuses on basal cell carcinoma, a variety of skin cancer associated with hair follicle cells.
Chronic wounds significantly decrease the quality of life of patients by requiring continuous topical treatment, causing immobility and pain in a high percentage of patients. Chronic wounds affect elderly population.
WHAT DOES A MALIGNANT WOUND LOOK LIKE? Malignant wounds may start out as small painless lumps, which may be pink, red, violet, blue, brown, or black in color, or normal in skin color. As the cancer grows the lumps will get bigger and mess with your skin's blood and lymph vessels.
You might have radiotherapy treatment for ulcerating cancers. Radiotherapy can help to shrink the cancer, dry it up and heal the wound to control pain and bleeding. It won't cure your cancer but can keep it under control. Your doctor might recommend that you have antibiotics as well as the radiotherapy.
Although not an all-inclusive list, some of the more common complications include infection, tissue necrosis and gangrene, periwound dermatitis, periwound edema, osteomyelitis, hematomas, and dehiscence.
Flat, firm, pale or yellow areas, similar to a scar. Raised reddish patches that might be itchy. Small translucent, shiny, pearly bumps that are pink or red and which might have blue, brown, or black areas.
What are the warning signs of melanoma?
Spread of pigment from the border of a spot into surrounding skin. Redness or a new swelling beyond the border of the mole. Change in sensation, such as itchiness, tenderness, or pain. Change in the surface of a mole – scaliness, oozing, bleeding, or the appearance of a lump or bump.
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.
The most common warning sign of skin cancer is a change on the skin, especially a new growth or a sore that doesn't heal. The cancer may start as a small, smooth, shiny, pale or waxy lump. It also may appear as a firm red lump. Sometimes, the lump bleeds or develops a crust.
At first, cancer cells appear as flat patches in the skin, often with a rough, scaly, reddish, or brown surface. These abnormal cells slowly grow in sun-exposed areas.
Malignant transformation of chronic leg ulcers is a rare but possible condition, with squamous cell carcinomas (SCC) being the most common tumour type developing in chronic leg ulcers [3].
Fungating cancer wounds are sometimes called malignant ulcers or ulcerating tumours. A fungating wound develops when cancer that is growing under the skin breaks through the skin and creates a wound.
First, the possibility of malignancy or infection in the wound often requires sampling of the wound edge and its bed. Secondly, several practice guidelines recommend biopsying wounds that have not responded to treatment after 2–6 weeks.
Chronic wounds heal very slowly because they do not advance through all the phases. Instead, chronic wounds seem to get stuck. They are unable to get past the inflammatory stage. This can lead to additional complications, such as wound infections, or even limb amputations.
A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time or wounds that do not heal within three months are often considered chronic. Chronic wounds often remain in the inflammatory stage for too long and may never heal or may take years.
Wounds being treated as part of palliative care, including malignant wounds, are a subgroup of chronic cutaneous wounds that are often complex and recalcitrant to healing and may not follow a predictable trajectory of repair despite standard interventions and treatment of the underlying malignancy.
How does malignant start out?
They develop when cells grow uncontrollably. If the cells continue to grow and spread, the disease can become life threatening. Malignant tumors can grow quickly and spread to other parts of the body in a process called metastasis. However, not all malignant tumors grow quickly; some can grow much slower over time.
A few skin lesions resemble malignancies. Lesions that are growing, spreading or pigmented, or those that occur on exposed areas of skin are of particular concern.
Nearly all skin cancers can be cured if found and treated early. Treatments include excision, cryotherapy, Mohs surgery, chemotherapy and radiation. Check your skin for any changes in size, shape or color of skin growths. See your dermatologist once a year for a professional skin checkup.
The life expectancy for a person living with such a wound is very short with an average of six to twelve months survival (Lo et al., 2008).
The dead tissue will fall off after 1–6 weeks, depending on the area treated. New, healthy skin cells will grow and a scar may develop. The healed skin will probably look paler than the surrounding skin.
Leave contaminated wounds, bites, and punctures open. Wounds that are sutured in an unsterile environment, or are not cleansed, irrigated, and debrided appropriately, are at high risk for infection due to contamination.
The most common types of chronic wounds include ulcers, infectious wounds, ischemic wounds, surgical wounds, and wounds from radiation poisoning. Ulcers are the most common type of chronic wounds.
As with acute wounds, local care of chronic wounds includes debridement and proper wound dressings. Frankly necrotic debris or nonviable tissue should be aggressively removed. Proper local care is an important element of preparing the wound bed to accept a skin graft or flap, or for closure, when indicated.
The most common type of melanoma usually appears as a flat or barely raised lesion with irregular edges and different colours. Fifty per cent of these melanomas occur in preexisting moles.
Diameter: There is a change in size, usually an increase. Melanomas can be tiny, but most are larger than the size of a pea (larger than 6 millimeters or about 1/4 inch). Evolving: The mole has changed over the past few weeks or months.
What do common skin cancers look like?
Basal cell carcinoma (BCC)
This is the most common type of skin cancer. BCC frequently develops in people who have fair skin. People who have skin of color also get this skin cancer. BCCs often look like a flesh-colored round growth, pearl-like bump, or a pinkish patch of skin.
General symptoms
hard or swollen lymph nodes. hard lump on your skin. unexplained pain. feeling very tired or unwell.
The first sign of melanoma is often a mole that changes size, shape or color. This melanoma shows color variations and an irregular border, both of which are melanoma warning signs. Melanomas can develop anywhere on your body.
Talk to your doctor if you notice changes in your skin such as a new growth, a sore that doesn't heal, a change in an old growth, or any of the A-B-C-D-Es of melanoma. A change in your skin is the most common sign of skin cancer. This could be a new growth, a sore that doesn't heal, or a change in a mole.
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.
Epithelial tissue is also the most common site for the development cancers. Carcinomas arise from epithelial tissue and account for as many as 90 percent of all human cancers. Two of the most common cancers in humans occur in breast and colonic epithelium.
Orange represents kidney cancer and leukemia. Green stands for liver cancer, lymphoma, and gall bladder cancer. Variations of purple signify pancreatic cancer, testicular cancer, leiomyosarcoma, Hodgkin lymphoma, stomach cancer, and esophageal cancer.

For example, certain types of skin cancer can be diagnosed initially just by visual inspection — though a biopsy is necessary to confirm the diagnosis. But other cancers can form and grow undetected for 10 years or more , as one study found, making diagnosis and treatment that much more difficult.
The majority of sun exposure occurs before age 18 and skin cancer can take 20 years or more to develop. Whether your sun bathing days are behind you or you still spend time pursuing the perfect tan, you should be concerned about skin cancer.
What chronic infections cause cancer?
- Epstein-Barr Virus (EBV)
- Hepatitis B Virus and Hepatitis C Virus (HBV and HCV)
- Human Immunodeficiency Virus (HIV)
- Human Papillomaviruses (HPVs)
- Human T-Cell Leukemia/Lymphoma Virus Type 1 (HTLV-1)
- Kaposi Sarcoma-Associated Herpesvirus (KSHV)
- Merkel Cell Polyomavirus (MCPyV)
- Helicobacter pylori (H. pylori)
The most common pathogens that cause wound infections include: Bacteria – the most-common pathogen, including Staphylococcus (staph), Streptococcus (strep), MRSA, Clostridium, Cellulitis, to name a few. Fungi – yeast and mold including Candida, Cladosporidium, and Aspergillus, among others.
Perhaps the biggest risk of improper wound care is infection. Skin is a protective barrier against bacteria and other foreign invaders. While it is open, bacteria can enter and multiply inside, causing an infection. An infected wound will ooze pus, feel warm, and be painful.
More recently, infections with certain viruses, bacteria, and parasites have been recognized as risk factors for several types of cancer in humans. Worldwide, infections are linked to about 15% to 20% of cancers.
There are many conditions that can cause masses or lumps in soft tissue that have nothing to do with tumors. An infection or abscess is perhaps the most common cause behind a mass that is mistaken for a tumor.
Although sepsis alone may not cause cancer, it is possible that underlying medical conditions that predispose to sepsis, the health consequences of sepsis, and the treatment of sepsis could be associated with cancer development through a range of mechanisms [8, 9].
- Diabetes, anemia, cancer and other long-term medical conditions.
- Heart issues, such as high blood pressure, heart disease or varicose veins.
- Immobility, such as being confined to a wheelchair or bed.
- Unhealthy habits such as smoking, not eating a healthy diet or not being active.
Chronic wounds heal very slowly because they do not advance through all the phases. Instead, chronic wounds seem to get stuck. They are unable to get past the inflammatory stage. This can lead to additional complications, such as wound infections, or even limb amputations.
a wound infection. a blood infection, or sepsis.
Individuals living with a chronic wound can experience chronic pain, loss of function and mobility, increased stress, social isolation, depression and anxiety, prolonged hospitalization, and even a higher risk of death.
How long is too long for a wound to heal?
It's not healing
A chronic wound is any wound that lasts longer than three weeks, but Dr. Yaakovian says wounds should start showing signs of improvement within a few days. "If your wound isn't healing after two or three days, we start to worry whether it may end up being a chronic wound," says Dr. Yaakovian.
