Skin cancer – Types and warning signs

Skin cancer is the most common type of cancer. It often develops on areas of the skin that are constantly exposed to the sun. Depending on the cells they affect, there are three major types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Each of these conditions may manifest differently. Knowing their warning signs can help one detect skin cancer early and manage it before it spreads.

Warning signs of basal cell carcinoma
This is the most common type of skin cancer. It forms in the basal cells of the skin, which lie at the bottom of the epidermis. It usually affects the sun-exposed areas of the body, such as the face and neck. Common signs and symptoms include a small pink or red bump that is shiny, pearly, or translucent and may have black, blue, or brown spots;
flat, flesh-colored, yellow, or brown scar-like lesion; lesions that bleed spontaneously without being irritated or picked; bleeding or scabbing open sore that doesn’t heal or heals and returns; pink growth with raised edges and a deflated center that may feature atypical blood vessels; and raised and itchy red patches.

Warning signs of squamous cell carcinoma
This is the second most common type of skin cancer, affecting over one million people yearly.

8 common early signs of cancer

Cancer, irrespective of the type, is a huge health concern around the world. Today, thanks to major improvements in screening technology, doctors are able to prove an early diagnosis of the condition, encouraging prompt and appropriate treatment. However, while keeping an eye out for the condition, one must remember that signs can vary depending on factors such as the size of the tumor, its impact on nearby organs and tissues, and its progression. Common early signs Fatigue Most people usually experience fatigue after exertion. But when dealing with cancer, the fatigue sets in without engaging in intense physical activities. Such exhaustion can hinder day-to-day activities. Just like normal cells in the body, the cancer cells thrive on nutrients to grow, leaving little for other healthy cells. This deprivation can make one feel extremely tired throughout the day. Changes in bowel movements One of the early warning signs of cancer is changes in bowel movement. Further, colorectal cancer affects the colon and rectum, causing symptoms like diarrhea and constipation, which can further contribute to fatigue. Such changes can be accompanied by persistent pain in the abdomen and pelvic region. Bloating While bloating can cause discomfort, most people believe it to be harmless.

12 warning signs of kidney cancer

The kidneys’ primary function is to filter blood and remove any harmful properties. However, individuals can develop masses such as growths or tumors inside the kidneys, which can stop them from doing their job properly. And while these could be signs of other health conditions, they may also indicate kidney cancer. Therefore, it is essential to learn about the signs of this mutation to receive a diagnosis as soon as possible. Here are a few signs that point toward kidney cancer: Blood in the urine (hematuria) The normal color of urine ranges from clear to pale yellow. Sometimes, this color may also change based on the foods one eats. For example, blackberries, beets, and fava beans may turn urine pink or red. Furthermore, certain treatment options may cause the color of the urine to turn orange or green. However, the reddish color of one’s urine might indicate that something isn’t right with the organ. It could point toward the presence of an infection or cancer. A healthcare expert must immediately diagnose such developments. Abdominal lump One of the most common indicators of kidney cancer is a hard lump that forms in the abdominal region. The development may occur in the front or rear of the region.

9 warning signs of lymphoma

Lymphoma is a form of cancer that originates in the lymphatic system, a vital part of the immune system. It arises when either of the two types of lymphocytes (T cells or B cells) begin to multiply uncontrollably. There are two main categories of lymphoma: Hodgkin and non-Hodgkin. Identifying the type is crucial for devising a suitable treatment plan. The following are a few common warning signs of the condition. Swollen lymph nodes Lymph nodes are a critical part of the lymphatic system, located in various body parts, including the neck, groin, armpit, and spleen. They filter lymph fluid to eliminate harmful substances and fight off infections. Lymphoma leads to an abnormal multiplication of lymphocytes, which, in turn, causes one’s lymph nodes to enlarge and swell. As a result, one may notice swelling in the spleen, neck, armpits, or groin, which does not go away. The swelling is usually painless but can be painful in some cases. Itchy skin Persistent and unusual skin itching can also be a warning sign of lymphoma. One may experience itching all over the body or near affected lymph nodes. Persistent and unexplained itching in the hands, legs, or feet could point toward lymphoma. The itchiness results from the release of certain chemicals called cytokines.
