Cancer-Related Symptoms
Cancer can present with a broad range of symptoms depending on its type and location — some well-known, others more subtle. This page lists key cancer-related symptoms such as unexplained weight loss, persistent fatigue, pain or changes in skin and organ function. Recognising symptoms early and discussing them with a healthcare provider can significantly improve the chances of diagnosis and successful management of cancer. Stay informed, stay vigilant, and don’t hesitate to act if you notice persistent changes in your health.
Anemia
Anemia is a common cancer-related condition where low red blood cell levels cause fatigue, weakness, and shortness of breath.
Anxiety
Anxiety is a common emotional response in cancer patients, causing persistent worry, tension, and fear that can affect daily life and treatment experiences.
Appetite Loss
Appetite Loss is a symptom often seen in cancer patients, leading to reduced food intake, weight loss, and malnutrition.
Ascites
Ascites is the buildup of fluid in the abdomen, which can occur when cancer spreads or affects liver function.
Bleeding and Bruising
Bleeding and Bruising are symptoms that may occur in cancer or as side effects of treatment, due to low platelet counts.
Bowel Obstruction
Bowel Obstruction is a blockage in the intestines that can result from abdominal or pelvic cancers interfering with digestion.
Cachexia
Cachexia is a cancer-related syndrome causing severe weight loss, muscle wasting, and weakness despite adequate nutrition.
Chills
Chills are episodes of shivering and cold sensations often linked to cancer infections or treatment side effects like fever.
Cognitive Dysfunction
Cognitive Dysfunction is a condition sometimes called “chemo brain,” involving memory and concentration problems during cancer treatment.
Pain
Pain is a common cancer-related symptom that may arise from the disease or its treatment, affecting physical comfort, daily activities, and overall quality of life.
Organ-Related Inflammation
Organ-related inflammation is a condition where specific organs become inflamed, potentially impairing function and leading to pain or other symptoms.
Nerve Problems
Nerve problems are disorders that affect nerve function, causing pain, numbness, weakness, or tingling due to damage or irritation of nerve.
Nausea and Vomiting
Nausea and vomiting are common cancer-related symptoms that may result from the disease itself as well as cancer treatments such as chemotherapy and radiation.
Constipation
Constipation is a common digestive condition characterized by infrequent bowel movements or difficulty passing stool due to slowed intestinal function.
Delirium
Delirium is a sudden state where the mind becomes confused, reality blurs, and awareness shifts unpredictably.
Muscle Weakness
Muscle weakness is a decline in physical strength and motor control caused by treatment toxicity, inactivity, or cancer-related fatigue.
Depression
Depression is a state where sadness deepens, motivation fades, and daily life feels heavy and exhausting.
Memory Problems
Memory problems involve cognitive lapses and mental fog that cancer patients may face as a result of treatment or emotional exhaustion.
Diarrhea
Diarrhea is a condition where frequent, loose stools occur, often causing discomfort, weakness, and dehydration.
Mouth and Throat Problems
Mouth and throat problems are complications like sores or dryness that occur when cancer therapies damage the lining of the oral cavity.
Dizziness
Dizziness is a feeling of lightheadedness, spinning, or imbalance that can make standing, walking, or focusing difficult and unsettling.
Dry Mouth
Dry mouth is a condition where saliva decreases, causing discomfort, difficulty swallowing, and a constant feeling of dryness in the mouth.
Joint Pain
Joint pain refers to the persistent stiffness and physical discomfort in skeletal joints often triggered by specific cancer therapies.
Fatigue
Fatigue is a prolonged state of physical and mental exhaustion where energy levels drop, concentration weakens, and even simple daily tasks feel overwhelming despite rest.
Fertility Issues in Females
Fertility issues in females involve disruptions in ovarian function or hormone balance, which may reduce the ability to conceive as a result of cancer treatments affecting the reproductive system.
Fertility Issues in Males
Fertility issues in males involve a reduction in sperm count or quality, often resulting from cancer treatments that affect hormone production or reproductive organs.
Infection and Neutropenia
Neutropenia is a critical drop in white blood cells that leaves the immune system unable to protect the body against harmful bacteria.
Hearing Loss
Hearing loss refers to a decline in auditory function that can occur when certain treatments damage the nerves or structures of the inner ear.
Fever
Fever is an elevated body temperature that may indicate infection or an inflammatory response, commonly observed as a side effect of weakened immune function during treatment.
Hair Loss
Hair loss is the partial or complete shedding of hair caused by damage to hair follicles, frequently associated with chemotherapy or radiation therapy.
