One in five people worldwide is expected to develop cancer during their lifetime. Behind that statistic are individuals, families, caregivers, and communities whose lives can be profoundly affected by a cancer diagnosis.
But cancer is not only a story about treatment.
It is also a story about prevention, awareness, early detection, timely diagnosis, and access to appropriate care.
As an oncologist, I believe that creating awareness is one of the most important steps we can take toward reducing the impact of cancer. The earlier we recognize risk factors and concerning symptoms, the earlier we can seek medical advice—and in many cancers, timely diagnosis can make a meaningful difference to treatment options and outcomes.
Cancer Awareness Begins Before a Diagnosis
When we talk about cancer, conversations often begin after someone has already been diagnosed.
I believe they should begin much earlier.
We should be talking about tobacco cessation, responsible alcohol use, healthy lifestyles, vaccination against cancer-associated infections such as HPV and hepatitis B, appropriate screening, and the importance of paying attention to persistent symptoms.
Prevention does not mean that every cancer can be avoided. Cancer is a complex disease influenced by multiple biological, genetic, environmental and lifestyle factors.
However, several important risk factors are modifiable.
Choosing not to use tobacco, limiting alcohol consumption, maintaining a healthy weight, staying physically active and following recommended vaccination and screening practices can all contribute to reducing cancer risk.
Don’t Ignore Persistent Symptoms
One of the most important messages I want to share is simple:
If something feels unusual and does not go away, get it checked.
A persistent symptom does not automatically mean cancer. Many symptoms are caused by infections, inflammation or other non-cancerous conditions.
But persistent or unexplained symptoms deserve appropriate medical evaluation.
Depending on the type of cancer, warning signs may include:
- An unexplained lump or swelling
- A sore that does not heal
- Unexplained bleeding
- Persistent changes in bowel or bladder habits
- Difficulty swallowing
- Persistent cough or hoarseness
- Unexplained weight loss
- Persistent pain without an obvious cause
- Changes in a mole or skin lesion
- Persistent changes in the mouth or throat
The important point is not to become fearful of every symptom.
It is to avoid unnecessary delay when a symptom persists.
Screening Can Help Detect Cancer Earlier
Screening is different from investigating symptoms.
Screening is performed in people who may not have symptoms, with the aim of identifying cancer or precancerous changes at an earlier stage.
The appropriate screening strategy depends on factors such as age, sex, family history, risk factors and the type of cancer being considered.
For example, screening approaches are available for certain cancers, including breast, cervical and colorectal cancers.
If you are unsure whether you require screening, speak with your healthcare provider rather than relying on generalized information from the internet.
A screening recommendation should always be individualized according to your risk profile and current guidelines.
A Cancer Diagnosis Is Not the End of the Story
The word “cancer” can be frightening.
I have seen the anxiety that patients and families experience when they first hear their diagnosis. Questions immediately follow:
What treatment will I need?
Will I recover?
Will I need chemotherapy?
Will I need radiation?
What will happen to my family?
These concerns are completely understandable.
But cancer treatment today is very different from what it was decades ago. Advances in surgery, systemic therapy, radiation oncology, imaging, pathology and supportive care have transformed the way we approach many cancers.
Treatment is increasingly individualized.
The goal is not simply to treat cancer, but to select the most appropriate treatment strategy for that particular patient.
The Role of Radiation Oncology
Radiation therapy is an important component of modern cancer treatment and may be used with curative or palliative intent depending on the individual clinical situation.
It can be used as the primary treatment for selected cancers, after surgery to reduce the risk of recurrence, alongside systemic treatment, or to relieve symptoms caused by advanced disease.
Modern radiation oncology has also evolved considerably.
Techniques such as IMRT, IGRT, VMAT, SBRT, SRS, SGRT and brachytherapy allow radiation treatment to be planned and delivered with increasing precision in appropriately selected patients.
But technology is only one part of cancer care.
The most important question is always:
What is the right treatment for this patient?
Cancer Care Is a Team Effort
Cancer treatment rarely happens in isolation.
Depending on the diagnosis, patients may need the expertise of a surgical oncologist, medical oncologist, radiation oncologist, radiologist, pathologist, nutritionist, physiotherapist, palliative care specialist and other healthcare professionals.
Multidisciplinary tumor boards allow specialists to discuss complex cases collectively and develop a coordinated treatment strategy.
For patients, this means that treatment decisions can be considered from multiple clinical perspectives rather than being based on a single aspect of the disease.
Don’t Let Fear Delay Treatment
One of the biggest barriers to early cancer care is fear.
Some people avoid consultation because they are afraid of hearing the word “cancer.” Others turn to unverified treatments or postpone medical evaluation while hoping that symptoms will disappear.
I understand that seeking medical advice can be frightening.
But delaying an evaluation does not make the problem disappear.
If cancer is not present, a consultation can provide reassurance and help identify the actual cause of the symptoms.
If cancer is present, an early diagnosis can provide an opportunity to begin appropriate treatment sooner.
Knowledge is not something to fear. It is something that gives us the ability to act.
Let’s Make Cancer Awareness a Community Mission
Cancer awareness cannot remain limited to hospitals and clinics.
It needs to reach our homes, schools, workplaces and communities.
We need to encourage our parents to undergo appropriate screening. We need to speak openly about tobacco use. We need to educate young people about HPV vaccination. We need to encourage people not to ignore persistent symptoms.
And we need to replace myths and fear with reliable medical information.
This is one of the reasons I am committed to cancer awareness and public education through Cancer Decoded with Dr. Geeta Singh.
My goal is simple: to make cancer information easier to understand and help people make informed decisions about their health.
What Can We Do Today?
Cancer awareness does not have to begin with something complicated.
Start with yourself.
Know your risk factors.
Avoid tobacco.
Limit alcohol.
Maintain a healthy lifestyle.
Follow recommended screening guidelines.
Know your family history.
Pay attention to persistent changes in your body.
And when something concerns you, seek appropriate medical advice rather than waiting and hoping it will disappear.
My Message to Every Family
Cancer affects far more than the person who receives the diagnosis. It affects parents, children, spouses, siblings, friends and caregivers.
That is why cancer awareness is everyone’s responsibility.
The global statistics remind us of the scale of the challenge, but statistics should not make us feel helpless. They should motivate us to act.
We can prevent some cancers.
We can detect some cancers earlier.
We can improve access to treatment.
We can continue advancing cancer therapies.
And we can support patients not only during treatment, but throughout their survivorship and recovery.
My commitment as a Radiation Oncologist is not limited to treating cancer. I also believe in creating awareness, encouraging timely evaluation, supporting informed decision-making and helping patients and families navigate their cancer journey with clarity and confidence.
This is a mission that becomes stronger when we do it together.
Share this message. Start a conversation. Encourage someone you care about to get the right medical advice.
Because sometimes, a simple conversation can be the first step toward early detection—and potentially, a life-changing difference.
