What is cancer and how does it develop?

Cancer is a disease in which abnormal cells grow uncontrollably and may spread to other parts of the body. It begins when the body’s normal cell cycle is disrupted, leading to the formation of tumors or abnormal blood cells.

What are the early warning signs of cancer?

Some common early signs include unexplained weight loss, persistent fatigue, lumps or swellings, changes in the skin or moles, long-lasting cough, abnormal bleeding, and changes in bowel or bladder habits. However, symptoms vary by cancer type.

Is cancer hereditary?

Some cancers can be hereditary. If a close family member has had certain types of cancer (like breast, colon, or ovarian), your risk may be higher. Genetic testing can help assess your personal risk.

What are the major risk factors for cancer?

Key risk factors include tobacco use, excessive alcohol consumption, obesity and poor diet, lack of physical activity, prolonged sun exposure, environmental toxins, and certain infections (e.g., HPV, hepatitis B/C).

Can cancer be prevented?

Not all cancers are preventable, but up to 30-50% of cases can be avoided through healthy lifestyle choices, regular screenings, vaccinations (like HPV), and avoiding carcinogens such as tobacco and processed foods.

What types of cancers do you treat at Ask Oncologist?

We treat a wide range of cancers, including breast cancer, lung cancer, colon cancer, prostate cancer, cervical cancer, oral cancer, and blood cancers such as leukemia and lymphoma. Our services cover diagnosis, staging, chemotherapy, and follow-up care under expert oncologist supervision.

Do I need a referral to consult a cancer specialist?

No referral is required. You can book a consultation directly through our website or by calling us. If you've had tests done already, bring the reports for a faster diagnosis.

Where is your clinic located and what are your consultation timings?

Dr. Pradeep Bhasker is available from 10 am to 5 pm at MediCover Hospital, Kakinada, and from 6 pm to 8 pm at Sivani Clinic. We recommend booking an appointment in advance to avoid wait times.

What should I expect during my first visit to an oncologist?

During your first visit, we’ll review your medical history, analyze any existing reports or scans, and may recommend further diagnostic tests if needed. A personalized treatment plan will be discussed based on your condition.

Can cancer be cured if detected early?

Yes, many types of cancer can be effectively treated or even cured if detected at an early stage. Regular screenings, awareness of symptoms, and early intervention improve survival rates significantly.

Understanding Radiation Therapy in Cancer Care By Dr. Pradeep Bhaskar, MBBS, DNB (Radiation Oncology), FIGRS Consultant Radiation Oncologist

Radiation therapy is one of the most effective and scientifically advanced treatments available for cancer care today. As a consultant radiation oncologist with a specialization in Stereotactic Radiosurgery (FIGRS), I have witnessed how precision-based radiation can target cancer cells with minimal harm to surrounding healthy tissue. For patients and their families seeking reliable cancer care, understanding how radiation therapy works can ease concerns and offer hope.

What Is Radiation Therapy?

Radiation therapy uses high-energy rays—such as X-rays, gamma rays, or charged particles—to damage the DNA of cancer cells. When this DNA is damaged beyond repair, the cells can no longer grow or divide and are gradually eliminated by the body. This approach is especially useful for tumors that are hard to reach surgically or located near vital organs.

As the best radiation oncologist in Kakinada, I often recommend radiation either as a standalone treatment or alongside surgery and chemotherapy, depending on the specific type and stage of cancer.

Purpose and Uses of Radiation Therapy

Radiation therapy serves multiple roles in cancer management:

Curative treatment: In early-stage cancers, radiation can eliminate tumors completely.
Adjuvant therapy: It helps destroy remaining cancer cells after surgery.
Palliative care: It reduces symptoms such as pain, bleeding, or obstruction in advanced cases.

This versatility makes it an essential part of comprehensive cancer treatment, especially when guided by an experienced team led by the best cancer specialist in Kakinada.

How Radiation Is Given

Radiation therapy can be delivered in two major ways:

1. External Beam Radiation Therapy (EBRT)

The most common method, where a machine targets the tumor externally. Modern techniques such as Stereotactic Radiosurgery (SRS) allow us to deliver high doses with pinpoint accuracy.

2. Internal Radiation Therapy (Brachytherapy)

Radioactive material is placed directly inside or near the tumor, offering a localized effect with minimal exposure to healthy tissues.

Being trained in SRS, I ensure patients receive the most advanced and tailored radiation plans, offering better outcomes with fewer side effects.

What Happens to Cancer and Healthy Cells?

Radiation damages the genetic material in both cancer and normal cells. However, cancer cells are more vulnerable and less capable of repairing themselves, which makes them more likely to die after treatment. In contrast, healthy cells are better equipped to repair the damage and usually recover over time.

Patients might experience some temporary side effects, but with proper care and monitoring, the healing of healthy tissues is well managed, ensuring a safe recovery path.

Recovery and Care After Radiation

Recovery from radiation therapy depends on several factors such as the type of cancer, location of the tumor, and overall patient health. Most patients experience:

Gradual disappearance of cancer symptoms.
Recovery of normal cell function in the treated area.
Improvement in quality of life as cancer shrinks or disappears.

At my clinic in Kakinada, we focus on a patient-centered approach that combines medical expertise, psychological support, and continuous follow-up, offering one of the most comprehensive radiation oncology services available in the region.

Conclusion

Radiation therapy remains a cornerstone in the fight against cancer. With today’s technology and expert planning, patients can undergo treatment with minimal discomfort and maximum effectiveness. If you or your loved one is navigating a cancer diagnosis, it’s essential to consult with a specialist who understands both the science and the patient journey.

As a consultant radiation oncologist and FIGRS-certified specialist, I am committed to offering the highest quality care. Whether you're searching for the best oncologist in Kakinada, the best radiation oncologist in Kakinada, or simply someone who listens and guides you through treatment, you are in the right hands.
