What Cancers Cause Itching Skin: Understanding the Link Between Cancer and Pruritus

Cancer is a term that makes people anxious and worried. When thinking of cancer, we often imagine extreme pain and discomfort in the body. But besides the physical agony, cancer can also cause skin irritation. Many cancer patients suffer from the constant itchiness, which can be unbearable at times. The sensation can be a result of the cancer itself or the treatments being undertaken. Several types of cancers have the potential to cause itchy skin, and it is essential to know what they are.

If you are experiencing persistent and unexplained skin itching, you must consult with a health professional. Skin changes or itching caused by cancer are often accompanied by other symptoms such as weight loss, fatigue, and lumps or bumps. In certain types of cancer, the itchy skin might appear before any other symptoms, making it crucial to act quickly. While the itching can be the result of other less severe conditions too, it’s always better to get it checked out as soon as possible. So, what cancers cause itching skin? This article will dive into this topic, helping individuals understand what to look for and what might be causing the underlying discomfort.

Early detection of cancer is crucial to improving the chances of a full recovery. And while it is common for certain types of cancer to cause itching skin, not everyone who experiences skin irritation is at risk for cancer. Skin irritation can be a result of dry skin, allergies, and even bug bites. In general, if you are experiencing itching that persists or makes you feel uncomfortable, it’s always best to seek medical attention. This article will help educate readers about what cancers cause itching skin by taking a closer look at the most common types, the associated symptoms, and what to expect during treatment.

Types of Cancers that Cause Itchy Skin

Itching skin is a common symptom of many types of cancer. Here are some of the most common cancers that are known to cause itchy skin:

  • Hodgkin lymphoma – This type of cancer affects the lymphatic system and can cause itchy skin, as well as swollen lymph nodes, fever, fatigue, and weight loss.
  • Non-Hodgkin lymphoma – This type of cancer also affects the lymphatic system and can cause itching skin, along with other symptoms such as swollen lymph nodes, fever, and night sweats.
  • Leukemia – This blood cancer can cause itchy skin, as well as bone pain, fatigue, and frequent infections.
  • Liver cancer – Liver cancer can cause itchy skin as a result of a buildup of bile acids in the body, which can happen when the liver is not functioning properly.
  • Biliary tract cancer – This type of cancer affects the bile ducts and can also cause itchy skin due to the buildup of bile acids in the body.
  • Pancreatic cancer – Itchy skin can be a symptom of pancreatic cancer, which can also cause abdominal pain, weight loss, and jaundice (yellowing of the skin and eyes).

If you are experiencing persistent itching skin, it is important to see a doctor to determine the underlying cause. In some cases, itchy skin may be a symptom of cancer, but it can also be caused by other conditions such as eczema, psoriasis, or an allergic reaction.

Symptoms of Cancer-Related Itching

Itching is one of the most common symptoms of cancer and can be caused by a variety of cancer types. The sensation can range from mild to severe and can be localized or spread all over the body. Below are the most common symptoms of cancer-related itching:

  • Widespread itching:
  • If you suffer from cancer-related itching, it typically spreads throughout the body. Although, it is more apparent on the trunk, arms, legs, and head in some cases. The skin may also appear red, dry, or swollen.

  • Intractable itching:
  • This type of itching is described as intense, and the sensation of being bitten or stung by insects or pins and needles. It tends to be more severe at night and can lead to a lack of sleep.

  • No observable rash:
  • In many cases, the itching will not have visible skin reactions like a rash. Scratching may lead to skin damage, lesions, or wounds, increasing the risk of infection.

Common Cancer-Related Itching Causes:

Itching related to cancer is often due to its effects on skin and organs. Here are some of the most common causes:

1. Tumor growth and invasion:

Cancers that develop or infiltrate the skin or other organs can trigger itching. The body perceives the cancerous cells as foreign and releases histamines, leading to itchiness. Greenberg et al. (2017), suggests that itching is an early indicator of melanoma and should not be ignored.

2. Treatment-related itching:

Treatment Type Description
Chemotherapy-induced rash and hives Chemotherapy drugs can cause skin irritation, resulting in rash-like symptoms and hives. The body’s immune system perceives the drugs as foreign substances, leading to itching.
Radiation dermatitis Radiation therapy causes direct skin exposure to high-energy radiation, leading to skin inflammation and itching.
Opiate-induced pruritus Opiates prescribed to manage cancer-related pain can lead to itching without a rash.

3. Hepatic disease:

The liver is responsible for removing toxins from the blood. When there is a liver disease, the organ does not function correctly, which leads to excess bile acid production that accumulates in the skin, leading to itching. Jaundice or yellowing of the skin is one of the common signs of liver cancer.

In conclusion, cancer-related itching can be a debilitating symptom for people with cancer, and identifying its underlying cause is vital for effective management. Patients should seek medical attention if they experience persistent or intractable itching.

The Mechanism of How Cancers Cause Skin Itching

Although itching can be a symptom of various cancers, the actual mechanism of how cancers cause skin itching is not yet fully understood. However, here are some of the potential reasons why cancer can cause itchy skin:

  • Release of histamines – Histamines are substances released by cells in response to injury or inflammation. Some cancer cells can release histamines, causing itching and other discomforts.
  • Inflammatory response – Cancer cells can trigger an inflammatory response that can contribute to itching. This response can cause the release of pro-inflammatory compounds, which can stimulate nerve endings and produce itching sensations.
  • Obstruction of blood or lymph flow – Some cancers, particularly those that affect the lymphatic system, can obstruct blood or lymph flow. This obstruction can cause fluid buildup, leading to skin itching and other symptoms.

Itching and Specific Cancers

Itching can occur with many different cancers, but some cancers are more likely to cause skin itching than others. For example:

  • Lymphoma – Some types of lymphoma can cause itching, particularly Hodgkin lymphoma and cutaneous T-cell lymphoma.
  • Leukemia – Itching is a relatively common symptom of leukemia, which affects the blood and bone marrow.
  • Liver cancer – Itching can be a symptom of liver cancer, which can affect the liver’s ability to function properly.
  • Lung cancer – Although less common, lung cancer can cause itching, especially if it metastasizes to the skin.

Treatment for Itching Caused by Cancer

The treatment for itching caused by cancer depends on the underlying cause. For example, if the itching is due to a buildup of fluid caused by lymphatic obstruction, treatment may involve drainage of the excess fluid. Antihistamines may help relieve itching caused by the release of histamines. In cases where cancer treatment itself is causing itching, the doctor may adjust the treatment plan or prescribe medications to help relieve the symptom.

Cancer type Potential causes of itching
Lymphoma Release of histamines, inflammatory response
Leukemia Release of histamines, inflammatory response
Liver cancer Obstruction of blood or lymph flow, release of bile salts
Lung cancer Inflammatory response, metastasis to the skin

It is essential to discuss any itching you experience with your doctor, especially if you have been diagnosed with cancer. Your doctor can help determine the underlying cause of the itching and develop an appropriate treatment plan.

How to Manage Itching Skin as a Symptom of Cancer

If you are experiencing itching skin as a symptom of cancer, it can be a frustrating and uncomfortable experience. However, there are ways to manage the itching and make it more bearable. Here are some tips to help:

Top Tips for Managing Itching Skin as a Symptom of Cancer

  • Keep your skin moisturized with a soothing cream or ointment. Avoid using products that contain fragrances, as these can be irritating to the skin.

Treating Itching Caused by Skin Cancer

Itching skin is a common symptom experienced by people with skin cancer, particularly those with certain types of skin cancers such as basal cell carcinoma, squamous cell carcinoma, and melanoma. Dermatologists and oncologists agree that itchy skin can be an unpleasant and distressing symptom for cancer patients, and it is important to seek medical attention to address the underlying cause.

  • Topical corticosteroids and antihistamines: These medications can help relieve itching by reducing inflammation and suppressing the histamine response that triggers itchiness. They may be prescribed in cream or oral form, depending on the severity of the symptom and the patient’s condition.
  • Moisturizers and emollients: Dry skin and irritation can exacerbate itching, so using a gentle moisturizer can help soothe the affected area and help prevent scratching. Patients should choose fragrance-free, hypoallergenic formulations to avoid further irritation.
  • Phototherapy: This treatment involves exposing the skin to ultraviolet (UV) light under controlled conditions. It can help reduce itching and inflammation in some cases, but it may not be appropriate for all patients, particularly those with a history of skin cancer or photosensitivity.

Patients with severe itching may need more aggressive treatment, such as systemic corticosteroids or immunosuppressive therapy. However, these treatments come with risks and side effects, so they are typically only used on a short-term basis and under close medical supervision.

It is important to avoid scratching or rubbing the affected area, as this can further damage the skin and increase the risk of infection. Patients should also avoid hot showers or baths, which can exacerbate itching, and wear soft, loose clothing to minimize irritation.

Treatment Pros Cons
Topical corticosteroids and antihistamines Relieve itching, reduce inflammation, and suppress histamine response May cause skin thinning, long-term use can lead to adverse effects, may not be effective for all patients
Moisturizers and emollients Help soothe and prevent scratching, reduce dryness and irritation May not offer sufficient relief for severe cases of itching, not a long-term solution
Phototherapy Can reduce itching and inflammation in some patients May not be appropriate for all patients, may have side effects such as photosensitivity, does not address underlying cancer

In conclusion, managing itching caused by skin cancer can be challenging, but there are several options available to relieve the symptom and minimize discomfort. Patients should work closely with their healthcare provider to determine the most appropriate treatment plan based on their individual condition and medical history.

Non-Skin Cancers that Can Also Cause Itching

Itching skin can also be a symptom of various non-skin cancers. Here are six common types of cancer that may cause itching:

  • Liver cancer: Itching is a common symptom of liver cancer, often caused by an increase in bilirubin levels in the body.
  • Bile duct cancer: Itching is also a common symptom of bile duct cancer, which can cause bile to build up in the body and lead to skin irritation.
  • Leukemia: Itching skin is a rare symptom of leukemia, but can occur due to the buildup of leukemic cells in the skin or the release of chemicals by the cancer cells.
  • Lymphoma: Itching skin is a common symptom of lymphoma, often caused by the buildup of lymph fluids in the skin or the presence of chemicals released by the cancer cells.
  • Pancreatic cancer: Itching skin is a rare symptom of pancreatic cancer, but can occur due to the release of histamines by the cancer cells or the obstruction of bile.
  • Lung cancer: Itching skin is a rare symptom of lung cancer, but can occur due to the release of chemicals by the cancer cells or an allergic reaction to the cancer itself.

Other Symptoms to Watch For

Itching skin may be just one of the symptoms of cancer. It’s important to watch for other symptoms that could indicate the presence of cancer, including:

  • Unexplained weight loss
  • Fatigue
  • Persistent cough
  • Bleeding or discharge
  • Changes in bowel or bladder habits
