Understanding Cancer& Treatments
Understanding your diagnosis, treatment options and recovery journey
A cancer diagnosis often introduces a completely new vocabulary and many unfamiliar treatments.
Patients and families are frequently asked to make important decisions while trying to understand complex medical information. Terms such as chemotherapy, immunotherapy, targeted therapy, radiotherapy and hormonal therapy can feel overwhelming, particularly at a time when emotional and physical demands are already high.
The aim of this section is to provide clear, accessible information about cancer, the treatments used in modern oncology, and some of the common challenges people may experience during and after treatment.
Understanding what is happening, why treatments work and why side effects occur can help patients feel more informed, confident and prepared throughout their cancer journey.
What Is Cancer?
Cancer is not a single disease but a group of conditions that share a common characteristic: cells begin to grow and divide in an uncontrolled way.
Under normal circumstances, the body carefully regulates how cells grow, repair themselves and eventually die. This process allows tissues and organs to function normally throughout life.
Cancer develops when changes occur within the genetic material (DNA) of a cell. Over time, these changes can allow cells to ignore the normal signals that regulate growth and repair.
As these abnormal cells continue to multiply, they may form a tumour or spread to other parts of the body.
Why Does Cancer Develop?
Cancer usually develops through a combination of factors.
These may include:
• Ageing
• Genetic predisposition
• Smoking
• Alcohol
• Environmental exposures
• Chronic inflammation
• Viral infections
• Random genetic changes that accumulate over time
In most cases, cancer develops over many years rather than appearing suddenly.
Benign and Malignant Tumours
Not all tumours are cancerous.
Benign tumours
Benign tumours remain localised and do not spread to other parts of the body.
Malignant tumours
Malignant tumours have the ability to invade surrounding tissues and may spread to distant organs through a process called metastasis.
It is this ability to spread that makes cancer potentially life-threatening.
What Is Metastasis?
Metastasis occurs when cancer cells leave the original tumour and travel through the bloodstream or lymphatic system to establish new tumours elsewhere in the body.
For example:
-
Breast cancer may spread to bone, liver or lungs.
-
Prostate cancer commonly spreads to bone.
-
Colorectal cancer may spread to the liver.
Modern cancer treatments are often designed not only to treat the primary tumour but also to prevent or control metastatic disease.
Why Are There Different Cancer Treatments?
Cancer is extremely complex.
Different cancers behave differently, grow at different rates and respond differently to treatment.
For this reason, modern oncology uses a range of treatment approaches.
Each treatment has specific strengths, limitations and potential side effects.
Main Types of Cancer Treatment
Surgery
Removal of cancerous tissue.
Often used when the cancer is localised.
Hormonal Therapy
Used for cancers that depend on hormones to grow, such as some breast and prostate cancers.
Antibody-Based Therapies
Use specially designed antibodies to target cancer cells with great precision.
Radiotherapy
Uses targeted radiation to damage cancer cells and prevent them from reproducing.
Targeted Therapies
Designed to block specific molecular pathways used by cancer cells.
CAR-T Cell Therapy
Uses the patient's own immune cells, genetically modified to recognise and attack cancer.
Chemotherapy
Uses medicines that target rapidly dividing cancer cells.
Immunotherapy
Helps the immune system recognise and attack cancer cells.
Why Do Side Effects Occur?
Many cancer treatments work by damaging cancer cells.
However, healthy tissues may be affected as well.
This can lead to treatment-related side effects.
The type and severity of side effects vary considerably according to:
• The treatment received
• The dosage used
• The duration of treatment
• The individual's overall health
• Personal biological factors
Not everyone experiences the same challenges.
Common Treatment-Related Challenges
Many patients experience some combination of:
Cancer-related fatigue
Persistent exhaustion that is not fully relieved by rest.
Sleep difficulties
Problems falling asleep, staying asleep or achieving restorative sleep.
Skin and nail changes
Particularly during certain chemotherapy and targeted therapy treatments.
Cognitive difficulties ("Chemo Brain")
Problems with concentration, memory, mental clarity and processing speed.
Digestive symptoms
Changes in appetite, nausea, bowel function and digestion.
Emotional disturbances
Managing uncertainty, stress and the practical consequences of treatment.
Peripheral neuropathy
Changes in sensation affecting hands and feet.
Mucositis
Inflammation or ulceration of the mouth and digestive tract.
Supportive Care During Cancer Treatment
Modern cancer care increasingly recognises that quality of life matters alongside treatment outcomes.
Supportive care aims to help individuals:
• Maintain function
• Improve comfort
• Strengthen resilience
• Manage treatment-related challenges
• Support recovery
• Adapt to life during and after treatment
Supportive care works alongside conventional oncology treatment and does not replace it.
How Rowan Health Supports Patients
At Rowan Health, supportive care is organised around personalised support protocols rather than standardised treatment packages. These protocols are developed according to the individual's diagnosis, treatment pathway, anticipated side effects, current symptoms and recovery goals.
Step 1 - Understanding the Treatment Pathway
We begin by understanding where each person is in their cancer journey (Surgery, chemotherapy, radiotherapy...)
Different treatments are associated with different challenges and recovery needs. A patient receiving oxaliplatin-based chemotherapy may face very different difficulties from someone receiving endocrine therapy after breast cancer treatment or recovering from CAR-T therapy.
Step 2 - Identifying Areas of Vulnerability
We then assess the factors most likely to affect quality of life, function and recovery.
(Fatigue, neuropathy, cognitive difficulties ("chemo brain"), sleep disruption, digestive symptoms, mucositis, pain, reduced physical function, emotional well-being...)
Our aim is to anticipate challenges before they become established whenever possible.
Step 3 – Building a Personalised Support Protocol
Based on this assessment, we develop a structured support plan tailored to the individual's needs and stage of treatment.
Depending on the individual's needs, the protocol may combine symptom management, rehabilitation, recovery support, education, self-management strategies and selected therapeutic interventions.
The emphasis is always on selecting the right combination of support for the right person at the right time.
Step 4 - Monitoring, Adapting & Supporting Recovery
Cancer treatment and recovery are dynamic processes.
Protocols are regularly reviewed and adapted as treatment progresses, symptoms change and recovery priorities evolve. The support required during active chemotherapy may differ significantly from that needed during rehabilitation, return to work or long-term survivorship.
Protocols are designed collaboratively with the patient and evolve throughout treatment and recovery.
Our Goal
Our objective is not simply to respond to symptoms as they arise.
It is to provide proactive, coordinated support that helps individuals:
-
Maintain function and independence
-
Strengthen resilience.
-
Reduce the burden associated with treatment
-
Improve quality of life
-
Facilitate recovery and rehabilitation
-
Navigate survivorship with confidence
By understanding the treatment pathway, anticipating likely challenges and adapting support over time, we aim to help patients navigate treatment and recovery as successfully as possible.
