While cancer has become a significant public health issue worldwide, it's not always fatal. Thanks to the advanced forms of cancer treatment such as radiation therapy or radiology that have undergone significant advancements. Focusing on the latest techniques, precision, and cutting-edge medical facilities, the experienced cancer doctor in Noida and Delhi treats cancer by targeting tumours more accurately while sparing healthy tissues to remain unaffected.

How Radiation Therapy Works
In this cancer treatment, medical practitioners use to ruin generic materials with cancerous cells so that they can't reproduce and spread. The cancerous cells lose the ability to overcome the damage, whereas normal cells can quickly repair themselves. This way, these weak cells become vulnerable to radiation.

Along with surgery and systemic therapies like chemotherapy, radiation oncology has become the primary anti-cancer tool for the treatment for lung cancer in Noida, brain cancer, breast cancer, liver cancer, prostate cancer and other types of cancer.

Let's have a look at some key developments in today's cancer treatment –

Image-Guided Radiation Therapy (IGRT)
IGRT uses advanced imaging technology to increase the precision of radiotherapy. In techniques like CT scans, ultrasound, integrated X-ray (KV) imaging, MRI and PET, IGRT helps to precisely and frequently locate and track tumours and healthy tissues just before and during treatments. This way, an experienced oncologist in Noida can adjust the radiation beam in real time, ensuring optimal accuracy and lessening damage to nearby healthy tissues.

Stereotactic Body Radiation Therapy (SBRT)
Stereotactic Body Radiation Therapy is emerging as an advanced cancer treatment technique, targeting tumours with extreme precision and very high radiation doses. In this method, the healthy tissues in the surroundings remain less affected, thus minimising the chance of side effects. This potentially curative therapy has proven effective for several tumours, including livers, lungs, and pancreas.

Stereotactic Radiotherapy
Stereotactic radiotherapy is very similar to SBRT, as in both stereotactic localisation techniques, high doses of radiation are delivered with extreme precision and target very specific areas. Stereotactic radiotherapy is used in the treatment of intracranial tumours located in the brain and spine, whereas SBRT is used for the treatment of tumours located outside of the brain and spine.

Spatially Fractionated Radiation Therapy (SFRT)

Another advanced radiotherapy technique is Spatially Fractionated Radiation Therapy or SFRT, which allows relatively high delivery doses. In contrast, the radiation doses vary for larger tumours while protecting healthy organs in the surroundings. 

SFRT comprises different techniques, such as grid radiotherapy and lattice radiotherapy. In the first technique, a combination of high and low doses of radiation is applied to a tumour with a physical block. A similar effect is applied using a computer model in the latter one.

Recent studies show that SFRT is effective in treating the early stages of cancer and is being used in the palliative treatment of lung and cervical cancers. In some cases, patients are provided a combined therapy with SFRT in inflammatory breast cancer treatment in Noida and several other locations.

Intensity Modulated Radiation Therapy (IMRT)
IMRT is an advanced type of 3D conformal radiotherapy where the tiny subdivision of beams called beamlets is assigned to conform to the tumour's shape. IMRT is especially effective when a tumour cannot be separated from the nearby organs at risk or has an irregular shape and when there is no practical use for allowing uniform-intensity beams. This radiotherapy innovation intends to treat complex tumours, diminishing the radiation effect on healthy tissues.

Volumetric Modulated Arc Therapy (VMAT)

As an advanced form of IMRT, volumetric modulated arc therapy is the technology that delivers sculptured 3D radiation dose from an arc with more precision. It is more targeted and more precise, helping to spare normal, healthy tissues. The machine's high cost is a hindrance to massive use of this technology by the oncologist in Delhi.

Robotic Radiotherapy
Compared to standard radiotherapy, robotic radiotherapy is far more advanced radiation therapy. Here, a frameless robotic radiosurgery system is used to deliver the radiotherapy to a specific body part more accurately from any direction. Robotic radiotherapy treats malignant and benign tumours and several other medical conditions.

Advancements of Radiation Oncology: To Wrap Up
It is undeniable that the field of radiation oncology has witnessed significant advancements in precision and technology. With cutting-edge advancements like nanotechnology and Artificial Intelligence (AI), radiation oncologists can provide more personalised, precise, and less invasive treatment. 

By combining advanced technologies with a deep understanding and experience, prominent cancer doctor in Noida, like Dr Manish Singhal, delivers more effective cancer treatment with a brighter future for cancer patients.
