Cancer Care

What is Cancer

Cancer is a disease characterised by the uncontrolled growth and spread of abnormal cells in the body. These cells can form tumours, which can be benign (non-cancerous) or malignant (cancerous). Malignant tumours can invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system, a process known as metastasis.
 

Types of Cancer
 

There are over 100 types of cancer, categorised based on the origin of the cancer cells.

Some common types include:

​

• Carcinomas: Cancers that begin in the skin or tissues that line or cover internal organs. Examples include breast, lung, and colorectal cancer.
   

• Sarcomas: Cancers that begin in the bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissues.
   

• Leukaemia's: Cancers that start in blood-forming tissue, such as the bone marrow, and cause large numbers of abnormal blood cells to be produced and enter the bloodstream.
   

• Lymphomas: Cancers that begin in the cells of the immune system.
   

• Central Nervous System Cancers: Cancers that begin in the tissues of the brain and spinal cord.
   

Common Symptoms of Cancer

Cancer symptoms can vary widely depending on the type and location of the cancer.

Some common symptoms include:

​

• Unexplained Weight Loss: Many people with cancer experience significant weight loss without trying.
   

• Fatigue: Persistent tiredness that doesn't improve with rest.
   

• Pain: Persistent pain, such as headaches or bone pain, can be an early or late sign of cancer.

  ​

• Skin Changes: Changes in the skin, such as new moles, sores that don't heal, or changes in existing moles.
   

• Unusual Bleeding or Discharge: Blood in the urine, stool, or unusual vaginal bleeding.
   

• Persistent Cough or Hoarseness: A cough that doesn't go away or hoarseness can be a sign of lung or throat cancer.
   

• Lumps or Swelling: New lumps or swelling in the breast, testicles, or other parts of the body.
  
  Stages of Cancer
   

• Cancer staging is a way to describe the extent of cancer in the body and whether it has spread. The most commonly used staging system is the TNM system, which stands for Tumour, Node, and Metastasis. Here's a breakdown of the stages:
  
  Stage 0:

• Carcinoma in Situ: Abnormal cells are present but have not spread to nearby tissue. This stage is not considered invasive cancer.
  
  Stage I:

• Early-Stage Cancer: The cancer is small and localised to one area. It has not spread to lymph nodes or other parts of the body.
  
  Stage II and III:

• Localised Spread: The cancer is larger and may have spread to nearby tissues or lymph nodes. These stages indicate more extensive disease but not distant spread.
  
  Stage IV:

• Advanced or Metastatic Cancer: The cancer has spread to other parts of the body, such as distant organs or tissues. This stage is the most serious.
  
  TNM System
  The TNM system provides more detailed information about the cancer:
   

• T (Tumour): Describes the size and extent of the main tumour. The primary tumour is usually measured and categorised from T0 (no tumour) to T4 (large tumour).
   

• N (Node): Indicates whether the cancer has spread to nearby lymph nodes. It ranges from N0 (no lymph node involvement) to N3 (extensive lymph node involvement).
   

• M (Metastasis): Refers to whether the cancer has spread to other parts of the body. M0 means no metastasis, while M1 indicates metastasis.
  
  Importance of Staging
  Staging helps doctors:
   

• Determine the most appropriate treatment plan.

• Predict the likely course and outcome of the disease (prognosis).

• Compare the effectiveness of different treatments.

• Identify clinical trials that may be suitable for the patient
  
  Managing and Living with Cancer
  
  Living with cancer can be challenging, but there are ways to manage the disease and maintain a good quality of life. Here are some key aspects to consider:
  
  Managing Cancer
  
  Medical Treatment:

• Treatment Options: Common treatments include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy. Each treatment has its own set of side effects and benefits.
  
  Side Effects Management:

• Managing side effects is crucial. This can include medications, lifestyle changes, and complementary therapies to alleviate symptoms like nausea, fatigue, and pain.
  
  Emotional and Psychological Support:

• Counselling and Support Groups: Talking to a counsellor or joining a support group can help manage the emotional impact of cancer.
  
  Mindfulness and Relaxation Techniques:

• Practices like meditation, yoga, and deep breathing can reduce stress and improve mental well-being.
  
  Practical Considerations:

• Financial Planning: Cancer treatment can be expensive. It's important to explore insurance options, financial aid, and support services.
  
  Advance Directives:

• Legal documents that state your wishes for medical care in case you are unable to communicate them.
  
  Living with Cancer
  
  Daily Life Adjustments:

• Diet and Nutrition: Eating a balanced diet can help maintain strength and energy levels. Some people may need to adjust their diet based on treatment side effects.
  
  Physical Activity:

• Staying active can improve physical and emotional health. Even light exercise like walking can be beneficial.
  
  Emotional Well-being:

• Coping with Emotions: It's normal to experience a range of emotions, including fear, anger, and sadness. Finding healthy ways to express and manage these feelings is important.
  
  Maintaining Relationships:

• Open communication with family and friends can provide emotional support and help them understand your needs.
  
  Long-term Management:

• Chronic Cancer: Some cancers can be managed as chronic conditions, with periods of remission and recurrence. Regular monitoring and treatment adjustments are key.
  
  Survivorship:

• After treatment, many people continue to face physical and emotional challenges. Follow-up care and support are essential for long-term well-being.
  
  Living with cancer is a journey that involves managing both the physical and emotional aspects of the disease.
  With the right support and resources, it's possible to maintain a good quality of life.
